Explanation:

The National Bank for Agriculture and Rural Development (NABARD) is a key financial institution in India. Here's how the shareholding structure works:

- Initially, NABARD was set up with 50% shareholding by the Government of India and 50% by the Reserve Bank of India (RBI).

- In 2005-06, RBI’s stake was transferred fully to the Government, making it 99%.

- If you see options given (150%, 251%, 375%, 499%, and 100%), the Government of India now holds 100% share in NABARD.

- The inconsistency in the given options likely stems from typographical errors or misunderstanding.

Correct Answer: 100%

The other figures mentioned aren't typically associated with shareholding structures.
