The correct answer is (c).
The Green Revolution was a period of agricultural development that began in the mid-20th century. It was characterized by the introduction of new agricultural technologies, such as high-yield varieties of crops and improved irrigation systems. These technologies led to a significant increase in crop yields, which helped to improve food security and reduce poverty in many parts of the world.
Wheat was one of the main crops that benefited from the Green Revolution. New varieties of wheat were developed that were more resistant to pests and diseases, and that could be grown in areas with less water. These new varieties of wheat helped to increase wheat production significantly, and made wheat a more affordable food source for millions of people.
Millet, pulses, and oilseeds are also important crops, but they did not benefit as much from the Green Revolution as wheat did. This is because these crops are often grown in areas with less favorable growing conditions, and they are not as susceptible to pests and diseases as wheat is. As a result, the Green Revolution did not have as significant an impact on the production of these crops.
In conclusion, the Green Revolution was a period of agricultural development that led to a significant increase in crop yields. Wheat was one of the main crops that benefited from the Green Revolution, while millet, pulses, and oilseeds did not benefit as much.
