In the question given below there are 2 statements marked as Assertion (A) and Reason (R). Choose the correct alternative from the following options.

Assertion (A)- Currently, the average temperature of Earth is rising.

Reason (R)- The depletion of Ozone layer has caused an increase in the UV radiations entering the Earth.

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

The correct option is Option 2: Both (A) and (R) are true but (R) is not the correct explanation of (A).

• Assertion (A) is true because the average temperature of Earth is rising due to global warming, primarily caused by the increase in greenhouse gases like carbon dioxide.
• Reason (R) is true because ozone layer depletion allows more UV radiation to enter the Earth, but this is not the direct cause of the rising average temperature. 
• However, while both statements are true, the reason does not directly explain the assertion. The primary cause of global warming is the increase in greenhouse gas emissions, not the depletion of the ozone layer. While ozone depletion has some impacts on the Earth's climate, it is not the main driver of global warming.
