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

If a mirror is placed on the line MN,

The circle on the right of the figure will be on the left in the mirror image

The triangle on the left of the figure will be on the right in the mirror image

The facing of the figure to the left and right direction changes to opposite direction in mirror image(right facing changes to left and vice versa)

$$\therefore\ $$The required mirror image is shown below

Hence, the correct answer is Option D
