Correct Option
The correct option is Liberalisation of foreign trade and investment.
Explanation
The year 1991 marks a watershed moment in the economic history of India. Faced with a severe Balance of Payments (BoP) crisis, the government introduced the New Economic Policy (NEP). This policy marked a paradigm shift from a closed, command-and-control economy to an open, market-oriented economy based on the principles of Liberalisation, Privatisation, and Globalisation (LPG).
Option Analysis
- Imposition of stricter trade barriers is Incorrect: The 1991 reforms aimed to integrate the Indian economy with the global economy. Consequently, trade barriers such as high tariffs and quantitative restrictions (quotas) were significantly reduced or removed, rather than made stricter.
- Liberalisation of foreign trade and investment is Correct: A central pillar of the 1991 reforms was the liberalisation of foreign trade and investment. This involved abolishing the industrial licensing regime (License Raj), reducing import duties, devaluing the rupee to boost exports, and opening sectors to Foreign Direct Investment (FDI) and Foreign Institutional Investment (FII).
- Ban on MNC operations is Incorrect: Prior to 1991, there were restrictions on Multinational Corporations (MNCs) under the FERA act. The reforms replaced FERA with FEMA (Foreign Exchange Management Act) and actively encouraged MNC operations and foreign technology agreements.
- Nationalisation of private industries is Incorrect: Nationalisation was a feature of earlier economic phases (e.g., bank nationalisation in 1969). The 1991 policy shifted focus towards privatisation and disinvestment of public sector undertakings (PSUs) to improve efficiency.
Key Takeaway: The 1991 economic reforms dismantled the "License Raj" and transitioned India towards a liberalised economy by promoting free trade, deregulation, and foreign investment.
