95.
The answer is: B
Explanation
The correct option is B: 2 years.
According to the Dissolution of Muslim Marriages Act, 1939 Section 2, one of the grounds for a woman married under Muslim law to obtain a decree for the dissolution of her marriage is that the husband has been insane for a period of two years or is suffering from a virulent venereal disease. This means that if the husband has been mentally unstable or afflicted with a serious sexually transmitted infection for two years or more, the wife can seek a divorce from him. The other options are incorrect because they do not match the duration specified in the Act.
