A Muslim woman needs to observe iddat in which of the following?

Iddat is the waiting period a Muslim woman must observe when her marriage ends by death or divorce. It applies on the dissolution of a valid (sahih) marriage, of an irregular (fasid) marriage once consummated, and of a muta marriage when its term expires or is remitted, so "All of the given options are correct". Its length, and whether it applies at all (for example where an irregular marriage was never consummated), depends on the type of marriage and how it ended.

Current law: Covered Uttarakhand marriages now require the UCC's statutory dissolution and remarriage rules, including sections 29-30, rather than treating the historical personal-law categories alone as the civil remarriage conditions. The Code commenced on 27 January 2025, subject to its exclusions.
