Answer:
C) acceleration.
Explanation:
The acceleration is changing.Because the direction of motion of car is changing from one direction to another direction.Till you are not able to understand the resolve the speed into vectors.
Initially there is no speed in right side after some time the speed at right side is 40 km/hr and in the initial direction is zero from here you can understand that the body is accelerating in right side and deccelerating in initial direction.
