The correct answer is (c) 60 days.
The Limitation Act, 1963, provides for the time limit within which a suit or appeal can be filed. Section 11 of the Act provides that an appeal against a decree passed by a district court in a suit under the Hindu Marriage Act, 1955, shall be filed within 60 days from the date of the decree.
Option (a) is incorrect because the limitation period for filing an appeal against a decree under the Hindu Marriage Act, 1955, is 60 days, not 30 days.
Option (b) is incorrect because the limitation period for filing an appeal against a decree under the Hindu Marriage Act, 1955, is 60 days, not 45 days.
Option (d) is incorrect because the limitation period for filing an appeal against a decree under the Hindu Marriage Act, 1955, is 60 days, not 90 days.
