As per the question, rays are falling on the mirror, which cleared that Regular reflection is taking place.
So, As per the laws of regular reflection.
=> ∠incident= ∠reflection
∠incident= ∠reflection=38Ao
Also we know that normal is at 90°to the mirror.
Now, to get the required angle we need to reduce angle of reflection from normal.
=>90Ao-38Ao=52Ao
so, the correct answer is option B.

Explanation:
Angle of Incidence and Angle of Reflection:
- The angle of incidence is the angle between the incident ray and the normal to the surface of the mirror at the point of incidence.
- The angle of reflection is the angle between the reflected ray and the normal to the surface of the mirror at the point of incidence.
Relationship between Angle of Incidence and Angle of Reflection:
- According to the law of reflection, the angle of incidence is equal to the angle of reflection.
- This means that if a ray of light strikes a mirror at an angle of 38°, the reflected ray will also make an angle of 38° with the normal.
Calculation:
- Given that the angle of incidence is 38°.
- Therefore, the angle between the normal and the reflected ray is also 38°.
Therefore, the correct answer is option 'A' - 38°.
