Answer:

Correct Answer: C

Solution:

The walls will act as two mirrors inclined to each other at 90

and so will form (360901)= 4 ? 1 i.e. 3 images of the person.

Now these images with person will act as objects for the ceiling mirror and so ceiling mirror will form 4 images further.

Therefore total number of images formed =3+3+1=7
