Under the Hindu Marriage Act, 1955, which of the following conditions makes a marriage void?

Section 5(i) of the Hindu Marriage Act requires "neither party has a spouse living", and breach makes the later marriage void under Section 11. A qualifying Section 5(ii) mental-capacity defect makes it voidable under Section 12, whereas age and registration do not themselves trigger HMA nullity; separate child-marriage legislation must also be considered.
