C Correct answer
Explanation

Angle = |30H - 5.5M|. For 7:30, H=7, M=30. Angle = |30*7 - 5.5*30| = |210 - 165| = 45 degrees.

AI explanation

Using the clock angle formula, the angle is calculated as 30 times the hours minus 5.5 times the minutes. At 7:30, the calculation is 30 times 7 minus 5.5 times 30, which equals 210 minus 165. This gives an angle of 45 degrees. The result is 45 degrees.
