The correct option is A 2:45
For mirror image main thing happens is left becomes right where as right becomes.As we know earlier in mirror image hours hand comes to left and vice versa for minutes hand.Hence making the time change from 9:15 to 3:45.When we rotate angle by 90 degree in clockwise time gets changed from 3:45 to 2:45.Because after rotating the arrow facing west will face towards east and arrow facing east will face towards west.Hence A is the correct answer.
