Answer:
A) Accelerating. You would not be aware of the motion if you did not look outside the car
Explanation:
Since human cannot sense the motion (unless visually), but the inertia force caused due to the acceleration of the motion. So if you are in a car with constant velocity, there's no acceleration and no inertia force, you would not be able to sense the motion at all unless you look outside.
