Question : Assertion: Global warming is primarily caused by the increase in greenhouse gas emissions.
Reason: Greenhouse gases trap heat in the Earth's atmosphere, leading to a rise in temperature.
Option 1: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Option 2: Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
Option 3: Assertion is correct, but the reason is incorrect.

Solution : The correct answer is (a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
The assertion states that global warming is primarily caused by the increase in greenhouse gas emissions, and the reason provided is that greenhouse gases trap heat in the Earth's atmosphere, leading to a rise in temperature.
Global warming refers to the long-term increase in Earth's average surface temperature, primarily attributed to human activities that release greenhouse gases into the atmosphere.
Therefore, the reason provided correctly explains why the increase in greenhouse gas emissions is the primary cause of global warming. The assertion and reason together support the understanding that human-induced greenhouse gas emissions contribute significantly to the observed global warming trends.
