Explanation
The correct answer is D: Religion, race, caste, language or any of them.
Article 29 of the Indian Constitution provides for the protection of interests of minorities by stating that any citizen of India having a distinct language, script or culture has the right to conserve the same. The article further specifies that no citizen shall be denied admission into any educational institution maintained by the state or receiving aid out of state funds on grounds only of religion, race, caste, language or any of them.
Therefore, Article 29 prohibits discrimination against any citizen of India on the basis of religion, race, caste, language, or any combination of these factors, in matters of admission to educational institutions that are either maintained by the state or receive aid from the state. This provision helps to promote equality and prevent discrimination in the field of education, which is a fundamental right of every citizen of India.
