Detailed Solution

Concept-  Whenever the hands move anticlockwise, we could assume that the time displayed is a mirror image of real time.
Imagine a line is drawn between the numbers 12 and 6 on the clock. It can be a line of symmetry.
When we mirror this clock, the hands on the right side of the line appear equidistant on the left side of the line, and vice versa.
The time is 8:25, with the hour hand on 8 and the minute hand on 5. Its mirror image will be the hour just before four o'clock and the minute hand on seven, i.e., 3: 35.
Hence, the correct answer is option 4) 03: 35.
