Correct Answer - C
(i) From the figures: i=r (first law of reflection). Angle made by the incident ray with the plane of mirror is `anglePOM=90-i=90-r" "(2)`
The angle made by the reflected ray with the plane of mirror =90-r " "(2)
(iii) `anglePOQ=anglePON+angleNOQ`
`=i+r=i+i(anglei=r)`
Angle between incident and reflected ray =2 (angle of incidence).
