Given:

The time shown in the mirror is 10 : 20.

In a mirror reflection of a clock, the actual time can be found by subtracting the mirror time from 11:60.

Actual Hour = 11 - Mirror Hour, Actual Minutes = 60 - Mirror Minutes

Actual Hour = 11 - 10 = 1

Actual Minutes = 60 - 20 = 40

Thus, the actual time is "1 : 40".

Hence, the correct answer is "Option 2".
