Explanation:

• The government introduced a new set of policy measures in the form of LPG (Liberalization, Privatization, and Globalization) reforms that changed the direction of our developmental strategies. 
• Reasons behind the 1991 economic reforms:
  • Inefficient management of the Indian economy in the 1980s. 
  • The inflation rate increased to around 16.7% due to the rapid increase in the money supply.
  • Rise in Fiscal Deficit due to the increase in non-development expenditure resulting in a rise of public debt and interest. Hence, Statement 1 is correct.
  • Interest liability became 36.4% of total government expenditure. 
  • Increase in adverse Balance of Payments. Hence, Statement 3 is correct.
  • Rising prices of essential goods. Hence, Statement 2 is correct.
  • Iraq War in 1990-91 led to a rise in petrol prices. The flow of foreign currency from Gulf countries stopped and this further aggravated the problem. Hence, Statement 4 is correct.
  • The dismal Performance of PSUs due to political interference and became a big liability for the government.
  • India’s foreign exchange reserve fell to a low ebb in 1990-91 and it was insufficient to pay for an import bill for 2 weeks.
