Which one of the following is not a ground of judicial separation under section 10 of the Hindu…

Section 10 of the Hindu Marriage Act, 1955 allows judicial separation on any of the grounds in Section 13(1) (and, for a wife, also those in Section 13(2)), which include adultery, cruelty and venereal disease in a communicable form. The presumed-death ground requires not being heard of alive for "seven years or more", so shorter absence alone does not establish that ground, though a separately proved ground such as desertion may exist.

Leprosy, formerly a ground under Section 13(1)(iv), was omitted by the Personal Laws (Amendment) Act, 2019.
