D Correct answer
Explanation

Angle = |30H - 5.5M|. H=4, M=20. Angle = |30*4 - 5.5*20| = |120 - 110| = 10 degrees.

AI explanation

Using the clock angle formula, the angle between the hour and minute hands equals 30 times the hours minus 5.5 times the minutes. Substituting the values for 4:20 gives 30 times 4 minus 5.5 times 20, which equals 120 minus 110, resulting in an angle of 10 degrees.
