Correct Option
The Constitution of India explicitly recognises and provides safeguards for both religious and linguistic minorities. While the term "minority" is not precisely defined within the Constitution, its provisions ensure their protection.
Article 29 protects the right of any section of citizens having a distinct language, script, or culture to conserve the same, thereby covering linguistic minorities. Article 30 grants all minorities, whether based on religion or language, the right to establish and administer educational institutions of their choice.
These articles collectively affirm the constitutional recognition of religious and linguistic minorities.
Incorrect Options
Options (a) "Only religious minorities" and (b) "Only linguistic minorities" are incorrect because the Constitution provides protection for both religious and linguistic minorities, not exclusively one over the other. Articles 29 and 30 extend safeguards to both categories.
Option (d) "Religious, linguistic and ethnic minorities" is incorrect because while religious and linguistic minorities are explicitly recognised, the Constitution does not specifically categorise or provide distinct provisions for "ethnic minorities" as a separate group.
