Answer 1

Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

Explanation:

Deforestation contributes to global warming by releasing stored carbon and reducing carbon dioxide uptake by photosynthesis. Methane and CFCs are greenhouse gases, but that fact does not explain the effect of deforestation.
