Option: 3

The acceleration vector points to the centre of the circle


Option: 4

The velocity and acceleration vectors are perpendicular to each other .

A particle moving in a circle with a constant angular speed has centripetal acceleration only and zero tangential acceleration.

As v=rw

\omega = constant\Rightarrow v=constant\Rightarrow a_t=0

Also centripetal acceleration, a_c=\omega^2r towards centre.

So, option b is wrong
