Explanation:

- Under Section 58 of the Code of Civil Procedure, the period of civil imprisonment for non-payment under a money decree depends on the amount owed.

- For a sum exceeding Rs. 2,000 but not exceeding Rs. 5,000, the maximum period of detention is three months.

- For sums exceeding Rs. 5,000, the period can extend to six months.

- If the sum is less than Rs. 2,000, the maximum detention is six weeks.

- Here are your options:

1. Six weeks (for less than Rs. 2,000)

2. Two months (not specified in the law)

3. Three months — this is the correct maximum period for Rs. 2,000 to Rs. 5,000

4. Six months (for above Rs. 5,000)

- Thus, the right choice for more than Rs. 2,000 but less than Rs. 5,000 is option 3.
