Question 7

A farmer family in Kerala consists of a husband, wife, and two minor children. The husband is a retired state government employee receiving a pension of ₹25,000 per month, and the wife owns 2 acres of agricultural land. They are not income tax payees. Considering the guidelines of the Pradhan Mantri Kisan Samman Nidhi (PM-KISAN) scheme, which of the following statements regarding their eligibility is correct?

Accepted Answer

C. The entire family is ineligible for the scheme because the husband is a retired government employee receiving a pension above the specified threshold. — The PM-KISAN scheme explicitly excludes farmer families where one or more members are retired government employees receiving a monthly pension of ₹10,000 or more (excluding Multi Tasking Staff / Class IV/Group D employees). Since the husband's pension exceeds this threshold, the entire family is ineligible for the scheme's benefits, irrespective of land ownership or income tax status. Other options incorrectly assume partial or full eligibility.

Answer

A. Both the husband and wife are eligible to receive separate benefits as they are a farmer family and own land.

Answer
