The answer is: A
Explanation
The correct option is A: 3 months from the date of decree .
This is because Section 82 of the Code of Civil Procedure (CPC) states that execution shall not be issued on any decree passed against the Union of India or a State or a public officer in respect of any act done in his official capacity, unless it remains unsatisfied for the period of three months computed from the date of such decree. This provision is intended to give the Government or the public officer sufficient time to consider the decree and decide whether to appeal against it or comply with it. The period of three months is fixed by law and cannot be extended or reduced by the court.
