Answer:
C. 27°
Explanation:
This question can be solved by using the concept of law of reflection which states that any ray of light reflects from the surface then angle of incidence is equal to angle of reflection.
In the problem given above angle of incidence as given is 27 degrees.
therefore by using law of reflection angle if reflection will be equal to angle of incidence i.e 27 degrees.
Thus, correct option is C. 27°
