The correct answer is: A) Rice and wheat.
The Green Revolution was a period of agricultural development that began in the mid-20th century. It was characterized by the introduction of new high-yield varieties of crops, such as rice and wheat, and the use of new agricultural technologies, such as irrigation and fertilizers. The Green Revolution had a significant impact on agricultural production in many parts of the world, but it had a lesser impact on Kerala due to the state’s focus on plantation crops, such as tea and coffee, rather than rice and wheat.
Plantation crops are crops that are grown on large plantations, often by multinational corporations. They are typically exported to other countries, and they generate a lot of revenue for the state. However, plantation crops are not as important for food security as rice and wheat, and they do not provide as many jobs for local people.
The Green Revolution also had a negative impact on the environment. The use of new agricultural technologies, such as irrigation and fertilizers, led to the depletion of water resources and the pollution of soil and water. In addition, the Green Revolution led to the displacement of many small farmers, who were unable to compete with large-scale commercial farms.
Overall, the Green Revolution had a mixed impact on Kerala. It led to an increase in agricultural production, but it also had a negative impact on the environment and on the livelihoods of small farmers.
