Which of the following pairs is correctly matched?

The correct answer is Option (3) → Secularism-communalism questions - the state's relationship to religion-based political groupings

Option (1) Inclusive vision of Indian nationalism - sought to do away with discrimination and exclusion — Incorrect. The pairing is reversed. Indian nationalism was inclusive because it recognised diversity and plurality; seeking to do away with discrimination and exclusion is what made it democratic.

Option (2) Democratic vision of Indian nationalism - recognised diversity and plurality — Incorrect. This pairing is also reversed. The democratic side of Indian nationalism sought to end discrimination and exclusion and bring a just society; recognising diversity and plurality made it inclusive.

Option (3) Secularism-communalism questions - the state's relationship to religion-based political groupings — Correct. Questions of secularism and communalism are about how the state relates to religion and to political groups that use religion as their main identity. The pair matches this.

Option (4) Most contentious aspect of cultural diversity - issues of regional and linguistic identity — Incorrect. The most contentious aspect of cultural diversity is issues of religious communities and religion-based identities. Regional and linguistic identity is a separate issue, taken up under regionalism.
