Question

The image of which of the following letters of the alphabet will be exactly the same when seen in a plane mirror: A E I O U

Answer 1

The image formed by a plane mirror is laterally inverted. Out of A E I O U, the letters I, O, and U are symmetrical about a vertical axis passing through their centers. So, even if the image of these letters will be laterally inverted, they would look exactly the same.
