Fundamental Rights in India come in two forms, those written out expressly in Part III, and those the courts have read into an existing provision through interpretation. Privacy belongs to the second category, and keeping that distinction in mind resolves this question quickly.
So the correct combination is that the Assertion is true while the Reason is false.
Before matching an option, it is worth pinning down two independent facts, whether the right to privacy actually flows from Article 21 through judicial interpretation, and whether the Constitution's text itself lists privacy as a distinct Fundamental Right. Once both facts are clear, only one option can be correct.
The Assertion is factually accurate about how privacy was recognised, while the Reason misdescribes it as an express textual right, so they cannot be paired as explanation and explained.
Hence, the correct answer is (A) is true, but (R) is false.
