Answer: (C) degrees/second

Explanation:

The rotational velocity must be a rate of units of rotation per unit of time. Rotations can be measured in "revolutions", "cycles", or "angle of rotation in degrees "

The only choice appropriately matching the above thought is (C) where the angle in degrees represents to the rotation count, per unit of time, i.e., 1 second.
