If a mirror is placed on the line AB, then which of the answer figure is the right image of the given figure?

A horizontal mirror is placed, so the figure will be reversed, that is, the triangles pointing upwards will face down and vice-versa, and thus the second and third options are not possible.

Also, the triangle on the left will remain at the left-hand side in the output, so the last option is also eliminated.

Thus, first is the correct output.
