1. Statement 1 is incorrect. After the liberalization of economic policies in 1991, the share of agriculture in India's GDP generally decreased, not increased enormously. The growth was primarily driven by the services and industrial sectors. 2. Statement 2 is correct. The liberalization policies, including trade reforms, helped India integrate better with the global economy. Consequently, the share of India's exports in world trade increased, although it started from a very low base. 3. Statement 3 is correct. Economic liberalization involved significant reforms to attract foreign capital. As a result, FDI inflows into India increased substantially in the post-1991 period. 4. Statement 4 is correct. One of the major outcomes of the economic reforms and improved balance of payments situation was a significant build-up of India's foreign exchange reserves. They increased enormously compared to the critically low levels seen during the 1991 crisis. 5. Therefore, statements 2, 3, and 4 are correct.
