Solution
The correct option is A MATH
We know that the image formed by a plane mirror undergoes lateral inversion.
Thus, the images of a letter will appear to be the same as the letter itself if that letter is symmetrical about the vertical axis.
Those letters are A, H, I, M, O, T, U, V, W and X.
The other letters, on reflection, wouldn't form a readable letter due to lateral inversion.
Thus, any word that is made of the above mentioned letters only can make a sequence of readable letters on inversion.
The word, among the options, is MATH.
