# The direction of the angular velocity vector is along

(a)the tangent to the circular path b) the inward radius c) the outward radius d) the axis of rotation.

angular velocity is a vector quantity describing an object in circular motion; its magnitude is equal to the speed of the particle and the direction is perpendicular to the plane of its circular motion.
Hence' d' is the correct option
