If government refuses security to a community only on the basis of identity which principle is affected?

Correct answer: Right to equal protection

The direct answer is A, Right to equal protection. Equal protection means that the government must protect people fairly, without denying help merely because of religion, caste, language, ethnicity, or another identity. Step by step: the government has a duty to provide security; the refusal is based only on identity; people in a similar need are therefore treated unequally; this violates equal protection and the wider idea of equality before law. Option A is correct because it names the affected right. Option B, an election slogan, is only a campaign phrase and is not a constitutional principle. Option C, a polling holiday, concerns the voting schedule and has nothing to do with security discrimination. Option D, tax collection, concerns raising public money, not equal treatment or protection. A democratic government must serve every citizen impartially. Memory cue: identity-based denial of protection means unequal protection.
