Correct Answer:
A. 25(2)
The correct answer is 25(2). Article 25(2) of the Constitution explicitly prohibits discrimination on the basis of sex alone, ensuring equality before the law and equal protection of the law for all citizens. This is a foundational principle of non-discrimination.
Distractor 26(1) deals with non-discrimination in respect of access to public places, while 27(1) addresses safeguards against discrimination in services, both of which include sex as a prohibited ground but are more specific than the general prohibition in 25(2). 28 pertains to the preservation of language, script, and culture, which is unrelated to discrimination on the basis of sex.
