Correct answer: (a) Both (A) and (R) are true and (R) is the correct explanation of (A)
Explanation
- A
Both (A) and (R) are true and (R) is the correct explanation of (A)
(a) Both (A) and (R) are true and (R) is the correct explanation of (A). The stored key treats exclusive Supreme Court jurisdiction over the constitutional validity of Central laws as true, and the Court’s role as guardian of the Constitution as the reason that jurisdiction exists. (a) Official key.
- B
Both (A) and (R) are true but (R) is not the correct explanation of (A)
(b) Both true but (R) does not explain (A). The keyed reading is that guardianship is precisely why Central statutes are finally tested at the apex court, so (R) is not a side-note.
- C
(A) is true, but (R) is false
(c) (A) true, (R) false. Guardianship of the Constitution is a standard description of the Supreme Court; (R) is not treated as false on this key.
- D
(A) is false, but (R) is true
(d) (A) false, (R) true. That would deny exclusive Central-law jurisdiction. The stored letter keeps (A) true and tied to (R).
Summary. Official key is (a). Assertion and Reason are both taken as true, and the Supreme Court as guardian of the Constitution is the explanation offered for exclusive say on the constitutional validity of Central laws.
