What principle was the main topic of discussion in the case of Sarla Mudgal v. Union of India?
The first wife's legal rights if the Hindu husband later converts to Islam and weds a second time
How women in polygamous marriages are divided in terms of property rights
The recognition of "live-in" relationships under Hindu Law
The adoption rights of Hindu women post-divorce
The main problem in the Sarla Mudgal case was Hindu husbands who converted to Islam in order to remarry without divorcing their first Hindu wife. The first Hindu marriage is not dissolved by such conversion, the court ruled, and the second marriage would be invalid, making the husband guilty of bigamy under the Indian Penal Code. hence option A is the correct option.
