Between 3:00 am and 3:00 pm of the same day, the minute hand would make 12 complete revolutions, with each revolution is of 360º. Thus, the required degree = 12*360 = 4,320º

Solution:

The minute hand makes a complete turn every hour. Since each complete turn is 360 degrees and there are 12 hours between 3 am and 3 pm, the total number of degrees is 360 x 12 = 4,320.

Answer: D
