Answer

Explanation:

Step1: Use the right - hand rule

The right - hand rule for angular velocity: curl the fingers of your right hand in the direction of rotation. The thumb points in the direction of the angular velocity vector. For a clock - wise rotation (as seen from above the screw going into the ceiling), when we curl the fingers of the right hand in the clock - wise direction, the thumb points down.

Answer:

C. down
