Answer:
D. The forces acting on the car are equal because it is at rest.
Step-by-step explanation:
The forces acting on the vehicle are not equal or zero just because it is at rest. When a vehicle is stopped at a stop sign, there are multiple forces acting on it, including gravity, friction, air resistance, and the tension force from the road. These forces are constantly acting on the vehicle and are not zero just because the vehicle is stopped.
