Correct option is B
Ashok Hurra v. Rupa (1997) dealt with marriage nullity and divorce proceedings, especially the validity of ex parte divorce decrees and the scope of Article 142 of the Constitution. It did not touch upon the issue of Uniform Civil Code (UCC).
The other three cases are known for their references to the need for UCC:
(A) Mohd. Ahmed Khan v. Shah Bano Begum (1985): A landmark case where the Supreme Court emphasized the relevance of UCC while ruling on a Muslim woman’s right to maintenance under Section 125 CrPC.
(C) Sarla Mudgal v. Union of India (1995): Dealt directly with conflict of personal laws and conversion to Islam for second marriage. The Court strongly advocated for a Uniform Civil Code to avoid misuse of personal laws.
(D) John Vallamattom v. Union of India (2003): Challenged discriminatory provisions under Christian personal law, and the Court again highlighted the need for UCC for ensuring equality under law.
