It would have more kinetic energy at the start, resulting in greater potential energy at the bottom of the track.
Answer: Option A.
Step-by-step explanation:
The car at the race track will accelerate at point X. It will have more kinetic energy at the start because the car is at the slope and with time it will result in greater potential energy at the bottom.
As we go down towards the bottom of the track, the kinetic energy will get converted into potential energy because here the body starts coming at rest and is not moving.
