Centripetal acceleration is rate of change of tangential velocity. The direction of centripetal acceleration is always inwards along radius vector of the circular motion.

First option: A car moving down a straight road.

Here, there is no circular motion.

Hence, not the example of centripetal acceleration.

Second option: A ball dropped from a second-floor window.

Here, there is no circular motion.

∴ not the example of centripetal acceleration.

Third option: A girl running around a track

Here motion is circular but the radius vector is not constant

Hence, not the example of centripetal acceleration.

Fourth option: A tetherball swinging around its pole

Here, a ball is joined to a pole as shown here the radius vector is constant and the ball swinging around the pole.

Hence, it is a example of centripetal acceleration.
