Explanation
1. In India, personal laws related to marriage, divorce, inheritance, etc., are often governed by religious laws, although the Constitution allows for a Uniform Civil Code (Article 44, a Directive Principle).
2. Generally, Hindu personal law, codified via the Hindu Marriage Act, 1955, enforces monogamy for Hindus, making it illegal for a Hindu male to have more than one living wife.
3. Muslim personal law, as traditionally interpreted and applied in India, permits polygyny (up to four wives) for Muslim males under certain conditions, though this is subject to ongoing debate and legal scrutiny.
4. However, the state of Goa retained its Portuguese Civil Code of 1867 after its integration into India. This code applies uniformly to all communities in Goa, including Hindus and Muslims.
5. While the Goan code is not entirely 'uniform' in the sense envisioned by Article 44 (it has specific provisions for Catholics and other communities), it notably enforces monogamy for all communities, including Muslims. Some specific, limited exceptions regarding polygyny for Hindus existed under certain conditions in the original code but are generally considered non-applicable or defunct.
6. Therefore, in Goa, it is illegal for both Hindu and Muslim males to practice polygyny, differing from the general situation in other states where Muslim personal law might permit it. The question phrasing legal for a Hindu male and illegal for a Muslim male seems reversed or perhaps designed to be tricky, intending to highlight Goa where the law is uniform *against* polygyny for both (making it illegal for Muslim males unlike other states, while it's already illegal for Hindu males across India). However, if interpreted as finding a state where the situation described *exists*, it points to a misunderstanding or a flawed premise. Given the options, Goa is the state with significantly different personal law application compared to the rest of India regarding marriage across religions, making it the most likely intended answer despite potential ambiguity in the question's premise. Other states like Nagaland, Mizoram, and Arunachal Pradesh have special provisions but predominantly follow the general pattern concerning Hindu and Muslim personal laws on marriage.
