Explanation:

The Cultural and Educational Rights are enshrined in Articles 29 and 30 of the Indian Constitution.

1. Incorrect - While the Constitution protects the rights of minorities to preserve their language, script, and culture, it does not specifically state that it is the Government's responsibility to expose children of minority groups to their belief and culture.
2. Incorrect - The Constitution does not say that only children belonging to the minority group that has opened an educational institution can study there. These institutions are generally open to all but can reserve a certain number of seats for students from their own community.
3. Correct - Article 30 allows religious and linguistic minorities to establish and administer educational institutions, and they can reserve seats for members of their own community in these institutions.
4. Incorrect - The Constitution does not stipulate that minorities can demand that their children must only study in educational institutions managed by their own community.

So, the correct interpretation among the options given is that reservations can be made in the schools opened by linguistic and religious minorities for their children
