Do Newton's Law apply to motion inside your car?

A.Yes, but only when at rest.
B.Yes, but only when traveling at constant velocity or at rest.
C.No, never.
D.Yes, always.

So I tried answering the question with D at first because I was thinking that it is a car in motion so that Newton's Laws should apply to the car. But then it is wrong, so I thought about it again and I notice it said inside the car, so I was thinking maybe the third law doesn't apply since there isn't 2 object exerting on each other inside the car. But that was wrong again. I am not sure where it is just at rest that it applies or that it could be at rest or constant velocity. Could someone please explain to me why is that when it is "inside the car", Newton's Law doesn't applies always?
