SSC CHSL 6 Mar 2018 Shift 1 Paper

A vertical mirror is placed, so the object on the left will appear right in reverse position and vice-versa.
So the circle at the bottom left will be reversed and will now appear at bottom right.
Also, in the question figure, the slanted line is originating from bottom right corner, hence it will appear at bottom left side, hence fourth option is the right image.
