Given below are two statements labelled as Assertion (A) and Reason (R)
Assertion : Ozone layer serves as the protective layer from UV radiations
Reason: Ozone is more oxidising in nature than oxygen.
Select the most appropriate answer from the options given below:

Options

A. Both A and R are true R is the correct explanation of A.
B. Both A and R are true R is not the correct explanation of A.
C. A is true but R is false
D. A is false but R is true

Answer

To solve the given question, we need to analyze both the Assertion (A) and Reason (R) statements provided.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Ozone layer serves as a protective layer from UV radiations."
- This is true because the ozone layer absorbs the majority of the sun's harmful ultraviolet (UV) radiation, particularly UV-B and UV-C, thus protecting living organisms on Earth from potential damage.

2. **Understanding the Reason (R)**:
- The reason states that "Ozone is more oxidizing in nature than oxygen."
- This is also true. Ozone (O₃) is indeed a stronger oxidizing agent compared to diatomic oxygen (O₂). It can react with various substances, leading to oxidation.

3. **Analyzing the Relationship**:
- While both statements are true, we need to determine if the reason provided (R) correctly explains the assertion (A).
- The assertion is about the protective role of the ozone layer against UV radiation, while the reason discusses the oxidizing nature of ozone compared to oxygen.
- The reason does not directly explain why the ozone layer protects against UV radiation. Therefore, while both statements are true, the reason does not serve as a correct explanation for the assertion.

4. **Conclusion**:
- Based on the analysis, the correct answer is that both A and R are true, but R is not the correct explanation of A.

### Final Answer:
Both A and R are true, but R is not the correct explanation of A.
