Explanation:

- A warrant case, as per Section 2(x) of the Code of Criminal Procedure (CrPC), relates to serious offenses.

- Such offenses are punishable with severe penalties.

- Option 1: Exceeding three years – This seems too restrictive for defining warrant cases.

- Option 2: Exceeding two years – This is the correct threshold for warrant cases.

- Option 3: Exceeding one year – This is broader than the legal definition.

- Option 4: Exceeding one year but less than two years – Warrant cases encompass a wider range.

Option 2 is correct.
