Explanation:

Here’s the thing about the RBI guidelines for the Chief Compliance Officer (CCO) in banks:

- RBI says the minimum fixed tenure for a CCO should be 3 years.

- This is to make sure the CCO can stay independent and not get pushed around by top management too easily.

- The idea is, with a good tenure, the CCO gets time to build a proper compliance culture and not just tick boxes.

- Option 1 (2 years) is too short; it doesn’t give enough time for the CCO to settle in and make a difference.

- Option 3 (4 years), Option 4 (5 years), and Option 5 (6 years) aren’t specified by RBI—three is the magic number here.

So, with that, the correct answer is:

Option 2: 3 years
