Explanation:

- The Reserve Bank of India (RBI) recently changed the rules about how much ownership bank promoters can have in private banks.

- Previously, the limit for a promoter's stake was set at 15% of the bank's paid-up voting equity share capital.

- Option 1: 20% - This suggests an increase which is more than the current limit but not the new cap.

- Option 2: 23% - A slight increase compared to option 1, but still not the new cap.

- Option 3: 26% - Correct. RBI has raised the cap to this percentage.

- Option 4: 29% - Provides an even higher limit than the new rule allows.

- Option 5: 25% - Close to the new cap but not exact.

The correct answer is Option 3: 26%
