Solution

The correct option is D

If a body rotates with constant angular velocity implies that the body rotates equal angle about any line considered through the body. Therefore the angular velocity of the whole body will be ' $ω$ ' about any point on the body. That is why it is the angular velocity of the body as a whole.
