Question 6

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

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
