Explanation:

- The Minimum Support Price (MSP) is a policy tool used by the Government of India to ensure agricultural producers are safeguarded against any drastic fall in farm prices.

- MSP is announced for certain crops, including lentils, to incentivize farmers and bolster agricultural productivity.

- For the Rabi marketing season 2022-23, the government set the MSP for lentils to ensure farmers receive adequate compensation for their produce.

- Option:1, Rs. 1500: Much lower than the actual MSP, unlikely to be correct.

- Option:2, Rs. 4000: Lower than the MSP set for lentils.

- Option:3, Rs. 6500: Higher than the set MSP.

- Option:4, Rs. 4500: Does not match the MSP announced.

- Option:5, Rs. 5500: Correct MSP for lentils for the 2022-23 Rabi season.
