The correct option is C There is an increase in the income of farmers, which increases the need for industrial products and services.
The overall development of rural areas includes both agricultural and non-agricultural development. When farmers are able to earn a higher income, they can spend more to buy modern agricultural products like tractors, harvesters, sprayers, motors, and so on. This increases the demand for industrial products and services. As the other sectors grow, jobs in those sectors also increase.
