Given below are two statements one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): It is crucial to sustain Himalayan ecosystem.
Reason (R): Himalayan ecosystem is home to a number of indigenous tribes.
In the light of the above two statements choose the correct answer from the options given below:
- A.
Both (A) and (R) are true and (R) is the correct explanation of (A).
- B.
Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
- C.
(A) is true but (R) is false.
- D.
(A) is false but (R) is true.

Correct answer: B
In an Assertion-Reason item, evaluate the Assertion (A) and the Reason (R) independently for truth, and only when both are true ask a further, separate question: does R actually state the specific cause or basis for A, or is it simply another true fact about the same subject? A reason that is true but addresses a different aspect of the topic does not count as the 'correct explanation'.
Assertion (A): Government and scientific assessments (India's National Mission for Sustaining the Himalayan Ecosystem, one of the eight missions under the National Action Plan on Climate Change, and ICIMOD's Hindu Kush Himalaya assessments) establish that the Himalayan ecosystem regulates the region's climate, feeds major river systems, and holds enormous biodiversity -- so protecting it is indeed crucial. (A) is TRUE.
Reason (R): Census and tribal-affairs data confirm that Himalayan states are home to a substantial Scheduled Tribe population, so the claim that the ecosystem hosts indigenous communities is also accurate. (R) is TRUE.
Explanation link: the case made for sustaining the ecosystem rests on ecological grounds -- river systems, climate regulation, biodiversity, disaster resilience -- not on the demographic fact of tribal habitation. (R) states a true, separate fact about the region; it does not supply the reason (A) is argued to be crucial. So (R) is NOT the correct explanation of (A).
Both true with (R) as the explanation -- fails, because (A) and (R) rest on different grounds, as shown above.
(A) true, (R) false -- fails, because the tribal-population claim is factually documented, not false.
(A) false, (R) true -- fails, because ecological assessments affirm the ecosystem's conservation need, so (A) is not false.
Hence the correct choice is: Both (A) and (R) are true, but (R) is NOT the correct explanation of (A).
