The question is asking for displacement time graph. Since the car accelerated at the start and did not go back to its original position, option A is the correct option when compared to other options. Option B is definitely wrong as the car moves back to its original position in the end. Option C is wrong because the car did not stop there for some time before a sudden retardation. Option A shows the car undergone an acceleration, then moved at constant velocity and then slowed down and came to a stop. Hence, option A best describes the car motion.
