The mirror image of “HINT” is:

The correct answer is Option (4) → TИIH

In a mirror held beside a word, the order of the letters is reversed and each letter is turned left to right. H, I and T are symmetrical about an upright line through their middle, so they look the same in the mirror; N is not, so it turns into a reversed N (И). The image of HINT therefore reads T, И, I, H.

Tip: The capital letters that look the same in a mirror held beside them are A, H, I, M, O, T, U, V, W, X and Y. In the mirror image of a word, reverse the order first; then only the other letters need to be turned.
