To resolve this Assertion-Reason pair, it is enough to check two separate things: whether the Supreme Court actually treated privacy as folded into Article 21, and whether the constitutional text itself contains a separately titled privacy right.
The correct answer is (A) is true, but (R) is false.
A useful way to test the Reason in this question is to compare how the Constitution treats rights that are genuinely spelled out on their own, against how it treats privacy.
The correct answer is (A) is true, but (R) is false.
