Section 58(1)(b) CPC specifies that for money decrees between Rs.2,000 and Rs.5,000, the maximum detention in civil prison is 6 weeks. A decree of Rs.3,500 falls in this bracket — so detention up to 6 weeks is the correct scenario.

1. 1 Open CPC → Section 58(1)(b). Check the amount brackets: Rs.2,000-5,000 = 6 weeks max detention. Rs.3,500 falls in this range. Confirm option (B) — decree Rs.3,500, detention 6 weeks.
