Explanation:

- The Pradhan Mantri Kisan Samman Nidhi (PM-Kisan) provides income support to farmers.

- It aims to ensure a minimal and constant financial backup for small and marginal farmers in India.

- The Union Budget 2022-23 allocated specific funds for this scheme to support ongoing development.

- ?60,000 crore: This amount might not be sufficient for the expanding needs of the initiative.

- ?62,000 crore: While a considerable sum, it doesn't match the precise allocation figure.

- ?65,000 crore: This is above average but still not the exact budget allocation.

- ?68,000 crore: This is the correct amount

- ?70,000 crore: An even larger amount, but higher than what's budgeted.

. The correct amount allocated in the Union Budget 2022-23 for PM-Kisan is ?68,000 crore.
