Given below are two statements, one labelled as Assertion (A) and the other labelled as **Reason (R):** Assertion (A):** The Sun is visible to us about 2 minutes before the actual sunrise and about 2 minutes after the actual sunset. **Reason (R):** The refractive index of air layers in the atmosphere increases with altitude, causing the light rays from the Sun to bend away from the normal. Choose the correct option:

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 but R is true.
