Solution
The correct option is B 5
The image formed by a plane mirror is laterally inverted and therefore the letters get inverted about the vertical axis. The letters that are symmetrical about their vertical axis will look the same in the mirror. In the word EMPHATIC, such letters are M, H, A, T, and I. Therefore, option B is correct.
