Answer :

(4) rear view mirror Explanation: Rear view mirrors of carsare convex mirrors as they enable the driver to see a wide area of the road behind the car. The convex mirror makes the rays of a parallel beam diverge as if they were coming from its focus, thereby produdcing a diminished virtual image which the driver can see.
