Solution (c)
Explanation:
• Arunachal Pradesh shares an extensive international boundary with Myanmar, specifically in its eastern region. The border is marked by the Patkai Hills and other geographical features.
• Nagaland has a border with Myanmar to its east. The region is known for its close cultural and ethnic connections with tribes living across the border in Myanmar.
• Tripura shares its international boundary with Bangladesh, not Myanmar. This makes it geographically distinct from the other northeastern states in this context. (Option (c) is correct)
• Manipur shares a significant border with Myanmar in its eastern region. The Moreh-Tamu border crossing is a prominent trade and transit point between the two countries.

Solution (b)

Explanation:

• While aging does lead to a decline in the production of growth hormone (GH), which is essential for maintaining muscle mass and repair, this is not the direct cause of muscle cell death. (Option (a) is incorrect)
• Mitochondria are the powerhouses of the cell that provide the energy required for muscle contraction and repair. As humans age, the number and functionality of mitochondria in muscle cells decrease. This inability to support cellular energy demands leads to muscle cell death and, consequently, loss of muscle mass, a condition known as sarcopenia. (Option (b) is correct)
• While calcium is critical for muscle contraction, its absorption is more directly linked to bone density issues and not the primary cause of muscle mass loss. A decline in calcium absorption affects bones more significantly (e.g., osteoporosis). (Option (c) is incorrect)
• Lactic acid accumulates temporarily during high-intensity exercise due to anaerobic respiration and is cleared soon after. It does not accumulate over a lifetime or cause muscle mass loss as part of the aging process. (Option (d) is incorrect)

Solution (d)

Explanation:

• The Calcutta Session of 1920 was presided over by Lala Lajpat Rai. This session is historically significant for adopting Gandhi’s proposal for the Non-Cooperation Movement as the official strategy of the Indian National Congress.
• The Nagpur Session of 1920 was presided over by C. Vijayaraghavachariar. This session was critical as it formalized the Congress’s adoption of the Non-Cooperation Movement and redefined the Congress’s objectives to include Swaraj (self-rule).
• The Lahore Session of 1929 was presided over by Jawaharlal Nehru. It is one of the most iconic Congress sessions as it declared Purna Swaraj (complete independence) as the goal of the Congress. The tricolor was also unfurled at this session on the banks of the Ravi River.
• The Belgaum Session of 1924 is the only session presided over by Mahatma Gandhi as the President of the Indian National Congress. It holds historical importance because Gandhi used this session to address internal divisions within the Congress and focus on unity. His leadership emphasized the importance of swadeshi and khadi. (Option (d) is correct)

Solution (c)

Explanation:

• Traditional computers use bits that are binary (0 or 1). In contrast, quantum computers use qubits (quantum bits), which can exist in a state of 0, 1, or a combination of both simultaneously due to the phenomenon of superposition. This forms the basis of quantum computing and its superior computational abilities. (Statement 1 is correct)
• Quantum entanglement is a phenomenon where qubits are interconnected, such that the state of one qubit is dependent on the state of another, even when they are physically separated. This property allows quantum computers to handle parallel computations, as operations on one qubit affect others instantaneously. It significantly enhances computational power for specific tasks like factoring large numbers or simulating quantum systems. (Statement 2 is correct)
• In quantum computing, superposition allows a qubit to exist in multiple states (0 and 1) simultaneously, unlike classical bits. This enables quantum computers to process multiple inputs and perform complex calculations much faster than classical computers, particularly for problems involving optimization, cryptography, and large-scale data simulations. (Statement 3 is correct)

Solution (d)

Explanation:

• The World Meteorological Organisation (WMO), established in 1950, is a specialized agency of the United Nations (UN). Its primary mandate is to coordinate international efforts on meteorology, climatology, hydrology, and geophysics. WMO plays a critical role in ensuring the global sharing of weather, climate, and water-related data, supporting disaster risk reduction and environmental protection. (Statement 1 is correct)
• The WMO releases two key reports annually:
  • Greenhouse Gas Bulletin: Tracks concentrations of greenhouse gases in the atmosphere, such as CO₂, CH₄, and N₂O.
  • State of the Global Climate Report: Highlights key indicators of global climate trends, such as temperature anomalies, sea level rise, and glacier retreat.
• These reports help guide global climate action and inform stakeholders on the urgency of mitigating climate change. (Statement 2 is correct)
• The Early Warning for All initiative is a global program launched under the leadership of the WMO to ensure that every individual on Earth is protected by early warning systems by 2027. The initiative focuses on improving disaster preparedness and minimizing loss of life and property due to extreme weather events such as cyclones, floods, and droughts. (Statement 3 is correct)
