If appointment in a government institution is denied only on the basis of caste, which right is mainly affected?

Correct answer: Right to Equality

Direct answer: B is correct. The Right to Equality includes the principle that people should not face unjust discrimination and that public employment should provide equal opportunity subject to constitutionally valid provisions. In this question, the appointment is in a government institution, and caste alone is used as the reason for denial. That makes the central issue equality and discrimination in public employment. A is wrong because exploitation concerns practices such as forced labour, trafficking or prohibited child labour, not ordinary unequal selection of a job applicant. C is wrong because no religious belief, worship or religious practice is mentioned. D is wrong because cultural and educational rights protect cultural identity and certain educational interests, not this general employment question. A careful learner should also remember that constitutional law may permit certain special provisions for disadvantaged groups; therefore the question is about unjust denial solely because of caste, not every policy that considers social disadvantage. Memory cue: public job plus unfair discrimination means Equality.
