Therefore in the table,
a) 15 degrees
b) 50 degrees
c) 25 degrees
d) 80 degrees
e) 90 degrees( incident and reflected rays coincide in this case )​

Answer 1

15 degrees is your answer.

Answer 2

All options which you gave I think our angle of incidence is as per first law of reflection angle of incidence is always equal to angle of reflection so the answer will be 15° 50° 25° 80° and 90° respectively
