"The Narendra Modi led government has its task cut out. It will need to focus on agriculture technologies that can boost agricultural productivity, create value added farm products and tap "farm to fork opportunities" to ensure better realization for farmers. It will also need to create millions of micro entrepreneurs and thousands of economic clusters in rural India, besides investing in rural roads, rural electricity, irrigation networks and national cold chain grids.

Based on the following case study answer the questions below :

Which of the following policy instruments does not help in improving the agricultural market system in India ?

Import substitution

The correct answer is option (2) : Import substitution

Import substitution is a trade policy that focuses on replacing foreign imports with domestically produced goods. While it may have broader economic implications, it is not directly related to the improvements of the agricultural market system in India. The other options - Minimum Support Prices (MSP), maintenance of buffer stocks, and the Public Distribution System - are  directly related to agricultural markets and food distribution. These instruments are aimed at protecting the income of the farmers and providing foodgrains at a subsidised rate to the poor.
