Assertion (A): Scattering of light is the reflection of light from an object in all directions.
Reason (R): The colour of scattered light depends on the size of scattering particles and wavelength of light.

Options

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

Explanation

To analyze the given assertion and reason, we will break down the statements and evaluate their validity step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states: "Scattering of light is the reflection of light from an object in all directions."
- Scattering of light indeed involves the redirection of light rays in various directions when they strike small particles or molecules in the atmosphere. This definition aligns with the concept of scattering.

2. **Understanding the Reason (R)**:
- The reason states: "The color of scattered light depends on the size of scattering particles and wavelength of light."
- This statement is also true. The color of the scattered light is influenced by the size of the particles and the wavelength of the light. For example, Rayleigh scattering explains why the sky appears blue; shorter wavelengths (blue light) scatter more than longer wavelengths (red light).

3. **Evaluating the Relationship**:
- While both the assertion and reason are true, they are independent statements. The assertion describes what scattering is, while the reason explains the factors affecting the color of scattered light. The reason does not provide a direct explanation for the assertion.

4. **Conclusion**:
- Since both statements are true but the reason does not explain the assertion, the correct conclusion is that both A and R are true, but R is not the correct explanation of A.

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