Given below are two statements, one labelled as Assertion (A) and the other labelled as **Reason (R):** Assertion (A):** A ray of light passing from one medium to another of different optical density does not bend if it is incident normally at the boundary. **Reason (R):** The angle of refraction is always equal to the angle of incidence for any pair of media. 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.
