Which of the following collections of letters will look the same in t…

The correct answer is Option (2) → (A), (B) and (D) only

A letter looks the same in a mirror held beside it only if it is symmetric about an upright line through its middle, so that its left half is the mirror image of its right half.

Note: In a mirror held beside a word, the order of the letters is also reversed: (A) would read MHov8AXO in the mirror. None of the four collections reads the same backwards, so if each were read as a word, none of them would look the same. The question speaks of collections of letters, and the answer given by NTA takes the letters one by one: a collection is counted as looking the same when every letter in it looks the same in the mirror.
