Solution

The correct option is D the axis of rotation

v=ω×r

for a particle in circular motion v is along tangent, r is away from centre.

so ω should be along axis of rotation.


(OR)


Using the right hand rule, the direction of angular velocity is defined as the direction in which the thumb of your right hand points when you curl your fingers in the direction of rotation.
