Assertion (A): All minorities, whether based on religion or language, shall have the right to establish and administer educational institutions of their choice.
Reason (R): Institutions established by the minorities are not entitled to governmental aid and government is not under an obligation to give aid

Article 30 in The Constitution 0f India
1949 is Right of minorities to establish
and administer educational
institutions.
(1) All minorities, whether based on
religion or language, shall have the
right to establish and administer
educational institutions of their choice
(1A) In making any law providing for the
compulsory acquisition of any property
of an educational institution
established and administered by a
minority, referred to in clause (1), the
State shall ensure that the amount fixed by or determined under such law
for the acquisition of such property is
such as would not restrict or abrogate
the right guaranteed under that clause.

30(2)- (2) The state SHALL NOT, IN GRANTING AID to educational institutions, DISCRIMINATE against any educational institution on the ground that it is under the management of a minority, whether based on religion or language.
(THAT MEANS that State may give governmental aid to these institutions its just they mustn't discriminate while giving aid)
Thus it can easily be concluded that the given assertion is true and R' is false.
