Article 30 has two clauses, and this question hands you one clause as the assertion and a distortion of the other as the reason. Clause (1) gives minorities the right to establish and administer educational institutions of their choice. Clause (2) stops the State from discriminating against those institutions when it hands out aid. Line the statements up against those two clauses and the answer falls out.
A fair caveat: Article 30(2) does not hand every minority institution a cheque. The State can set aid policies and conditions that apply to everyone. What it cannot do is single out an institution for denial because a minority runs it. R goes far beyond the permissible statement and claims there is no entitlement at all, which is why it is false rather than merely incomplete.
Let's summarize:
A is true and R is false, so option (C) is the answer.
