Any forcible imposition of a language or religion on any group of people weakens national unity. Which of the following country is an example of this?

Sri Lanka and Bangladesh

The correct answer is Option 2: Sri Lanka and Bangladesh

The unwillingness of the Pakistani state to recognise the cultural and linguistic rights of the people of Bangladesh contributed to the formation of Bangladesh. Similarly, in Sri Lanka, the imposition of Sinhala as the national language became a major issue behind ethnic conflict. Both examples show how ignoring linguistic and cultural rights can weaken national unity.

NCERT: In the last three decades we have witnessed how non-recognition of the rights of different groups of people in a country can have grave implications for national unity. One of key issues that led to the formation of Bangladesh was the unwillingness of the Pakistani state to recognise the cultural and linguistic rights of the people of Bangladesh. One of the many contentious issues that formed the backdrop of the ethnic conflict in Sri Lanka was the imposition of Sinhalese as a national language. Likewise any forcible imposition of a language or religion on any group of people in India weakens national unity which is based upon a recognition of differences. Indian nationalism recognises this, and the Indian Constitution affirms this.
