but you have to add another 10 minutes as the oven was preheated for 10 minutes in which the cake was not in the oven.

As the other options are p.m., 5:00 is also p.m. As the cake was left out for 20 min, 5:00 - 0:20 = 4:40 p.m. The cake was roasting for 4 hours 15 mins, 4:40 - 4:15 = 0:25. 0:25 p.m. is 12:25 p.m.
