Daughter has become a coparcener by virtue of the Hindu Succession (Amendment) Act, 2005 under:

The daughter became a coparcener by birth under section 6(1) of the Hindu Succession Act, 1956, as substituted by section 3 of the Hindu Succession (Amendment) Act, 2005. The options name sections of the amending Act itself: its section 5 omitted section 24 of the principal Act, its section 6 amended section 30, and it has no section 6(1). So the correct answer is "None of the given options is correct".

Current law: Vineeta Sharma (2020) subsequently clarified that the father need not have been alive on 9 September 2005 for the daughter's statutory coparcenary right. The right remains in principal Act section 6, not amending Act section 6.
