Step-by-Step Solution

A mirror reverses the order of the digits and flips each digit left to right. In segment digits a flipped 2 looks like 5 and a flipped 5 looks like 2, while 0 and 1 stay the same. Undoing both steps on 02:15 gives 21:50. (02:15 is the reading as seen; 05:12 flips the digits but not their order; 12:05 reverses the order only.)
Answer: D) 21:50
