When a plane mirror is rotated through an angle ∅, the angle of incidence changes by ∅, and because the angle of reflection equals the angle of incidence, the reflected ray shifts by twice that angle, that is:
the change in the reflected ray will be= 2∅
so yes, the answer is 2∅(C)

When a plane mirror is rotated through an angle (θ), the reflected ray rotates through an angle of (2θ) in the same direction, provided the incident ray remains fixed. This is a fundamental principle of reflection.
