Analysis:
Let's analyze the situation to find out how many times the ray is reflected from mirror A.

Explanation:
1. Initial Reflection:
- The ray is incident on mirror B at an angle of 45°.
- It gets reflected and moves towards mirror A.
2. Reflection from Mirror A:
- The angle of incidence on mirror A will be equal to the angle of reflection from mirror B (45°).
- The ray will be reflected from mirror A towards mirror B.
3. Reflection from Mirror B:
- The ray will be reflected from mirror B and again move towards mirror A.
4. Reflection from Mirror A (2nd time):
- The angle of incidence on mirror A will again be 45° (equal to the angle of reflection from mirror B).
- The ray will be reflected from mirror A towards mirror B.
5. Reflection from Mirror B (2nd time):
- The ray will be reflected from mirror B and move towards mirror A.
6. Calculation:
- The ray will keep alternating between mirrors A and B, with each reflection changing its direction.
- Since the mirrors are 10 cm apart, the ray will travel a total distance of 20 cm before it reaches mirror B again.
- The ray will be reflected 5 times (2 reflections from mirror A and 3 reflections from mirror B) before reaching mirror B again.
Therefore, the ray is reflected 5 times from mirror A.
