Which article is for protection of interest for minorities in the domain of educational admission to any academic session?

Article 29

Option 4: Article 29

Here's why:

Article 26: This article guarantees the right to freely manage religious affairs, establish and maintain institutions for religious and other educational purposes, and manage such institutions. However, it doesn't specifically address minority rights in educational admissions.
Article 27: This article prohibits religious instruction in state-run educational institutions, but it doesn't focus on admissions.

Article 28: talks about Freedom as to attendance at religious instruction or religious worship in certain educational institutions

Article 29(1): This provides any section of the citizens residing in India having a distinct culture, language, or script, the right to conserve their culture, language and script. 

Article 29(2): The State shall not deny admission into educational institutes maintained by it or those that receive aid from it to any person based only on race, religion, caste, language, or any of them. This clause specifically prohibits discrimination in admissions based on various factors, including religion, language, etc., in institutions maintained by the state or those receiving aid from the state. This directly addresses the protection of minority rights during admissions.
