Solution

The correct option is B $1$
The 2 plane mirrors are held at right angles, that is, they are inclined at an angle of 90 degrees.
As we know that if 360/ 90 = 4 is a even no , the no of images is (360/90-1) = 3. In first two images the comb will be in his left hand, the image which is between those two images has the comb in his right hand.
Hence, the answer is one.
