Answer: C. Around 70%
Explanation: The RBI’s Handbook-based analysis highlights rising export concentration across a few States. Maharashtra, Gujarat, Tamil Nadu, Karnataka and Uttar Pradesh together contribute close to 70% of India’s export basket. This reflects stronger industrial clustering, logistics networks and supply-chain ecosystems in these hubs. It also indicates a widening regional gap where many other States remain less connected to global trade.

Answer: B. Injecting rupee liquidity into the banking system and managing excess dollar liquidity/forward premium
Explanation: In an OMO purchase, RBI buys government securities and releases rupees into the system, improving banking liquidity. A dollar–rupee swap provides rupee liquidity while simultaneously absorbing dollar liquidity from the market. This can help cool an elevated USD–INR forward premium and provide stability when forex interventions have been used to support the rupee. Hence, option B is correct.

Answer: A. Kashiwazaki–Kariwa Nuclear Power Plant

This also reduces repeated verification across departments and improves service delivery efficiency.

Answer: B. United States of America

Hence, the satellite is associated with the United States. This mission also highlights India’s growing role in the global commercial launch market.
