For a mirror image of an analog clock showing time h:m (where h < 12), the actual time is (11-h):(60-m). For 8:15, we calculate (11-8):(60-15) = 3:45. This works because mirror images appear reversed, and the sum of the actual time and mirror time equals 11:60 (which is equivalent to 12:00). Option D is correct. Option C would be correct if we simply subtracted from 12:00 without accounting for minutes.
