(C) (A) is true, but (R) is false.
The Chipko Movement successfully resisted deforestation, but it promoted community afforestation with indigenous species, not a "community afforestation campaign" — the Reason misstates it as a separate campaign, making (R) false.

The passage states: "The famous Chipko movement…has not only successfully resisted deforestation…but has also shown that community afforestation with indigenous species can be enormously successful." The Assertion (A) is correctly stated. However, the Reason (R) incorrectly describes the afforestation as a separate "campaign," which is a distortion of what the textbook says — the movement demonstrated this success, it wasn't a formal afforestation campaign. Hence, (R) is false, making option (C) correct. Watch for such subtle misrepresentations in Reason statements.
