Solution

The correct option is A Brighter
Correct answer is (a).

Total reflecting prism produces an image which is brighter than obtained by using a plane mirror, because one of its angle equal to 90 degree and each of the remaining two angles equal to 45, so if a ray of light strikes one of its faces perpendicularly, it enters the prism without any change of direction due to which the intensity of image formed by it decreases and makes the image more brighter.
