Correct Answer: Wheat

Solution : The correct answer is (a) Wheat.

The Green Revolution in India, which began in the 1960s, was primarily aimed at increasing the production of wheat. The agricultural strategy introduced high-yielding varieties of wheat, along with improved irrigation techniques and the use of fertilizers and pesticides. This led to a significant increase in wheat production and helped India achieve self-sufficiency in wheat production. The Green Revolution also had an impact on the production of other crops such as rice, but its initial focus and success were particularly notable in the case of wheat.
