• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

Answer: (B)

Deforestation results in an increase in greenhouse gases which retains more and more UV radiations and leads to global warming. Global warming is the warming/heating up of the earth's atmosphere. Greenhouse gases are the gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. There are four main gases are methane, CFCs, carbon dioxide, and nitrous oxides.

Therefore, the correct answer is option B.
