Correct answer: B. Discrimination based on caste, religion, gender, or identity
Explanation: The governing concept is equality before the law and equal protection of rights. It requires that people not receive worse treatment merely because of caste, religion, gender, identity, or another irrelevant personal characteristic. Option B is correct because preventing such discrimination is the central practical meaning tested here. Equality does not mean that every person must receive identical treatment in every circumstance; it means that distinctions must be relevant, fair, and non-discriminatory, while reasonable support may be provided to address disadvantage. Option A is a safeguard that equality supports, not the main form of discrimination being asked about. Option C is a legal duty, not the harm equality primarily prevents. Option D is part of a remedy process and is not itself the prohibited discrimination. Thus, equality protects equal status and respect.
