Which one of the following will be the same as its mirror image?

The correct answer is Option (1) → WYTOTYW

A mirror held beside a word reverses the order of the letters and turns each letter left to right. A word looks the same in the mirror only if every letter is symmetric about a vertical line (so it is unchanged when turned) and the word reads the same backwards. In WYTOTYW every letter is symmetric and the order is the same from either end.

Tip: The capital letters that look the same in a mirror are A, H, I, M, O, T, U, V, W, X and Y; a word made only of them still changes unless it also reads the same backwards.
