The correct answer is (a).
Marginal farmers are those who own less than one acre of land. They are the most vulnerable group of farmers in India, as they are often unable to make a living from their land. They are also more likely to be affected by droughts, floods, and other natural disasters.
The government of India has implemented a number of programs to help marginal farmers, such as providing them with subsidies on seeds, fertilizers, and irrigation. However, these programs have not been able to fully address the problems faced by marginal farmers.
In recent years, there has been a growing movement to support marginal farmers. This movement has called for the government to provide more assistance to marginal farmers, such as land reforms and debt relief. It has also called for the government to give more attention to the problems faced by marginal farmers, such as the lack of access to markets and credit.
The movement to support marginal farmers has had some success. The government has implemented a number of new programs to help marginal farmers, and it has also made some changes to the laws governing land ownership and credit. However, there is still much work to be done to address the problems faced by marginal farmers.
The other options are incorrect because they do not accurately reflect the definition of a marginal farmer. A marginal farmer is a farmer who owns less than one acre of land.
