The correct option is "1 only," as India is indeed a member of the International Grains Council (IGC), which facilitates international cooperation in the grain trade and helps to promote grain market stability. However, statement 2 is incorrect because membership in the IGC is not a prerequisite for a country to export or import rice and wheat; countries can engage in trade of these staple grains independently of their IGC membership status. This distinction highlights the structure of international trade mechanisms and agreements, which allows for varying degrees of participation in global markets.
