Explanation / Answer

Given : the force that accelerates the car is B)the force of friction of the road on the tires. When you press the accelerator, you increase the amountof fuel injected into the engine's cylinders. The burning of thefuel creates gaseous pressure, and the pressure pushes on thepistons. The pistons then push on the crankshaft, resulting in atorque that causes it to spin faster. The crankshaft is ultimatelyconnected to the wheels, and the wheels experiences a torque whichcauses them to spin faster. The friction of the tires against thepavement resists the torque, and the car experiences a force, equaland opposite that of the friction, that propels it forward.
