Suppose that we wish to find the "net force" on an automobile, in order to apply Newton's law of motion to the motion of the automobile. As part of the net force, do we need to include "internal frictional forces" due to internal gears, bearings, etc.?       

A) Yes, because these forces dissipate some of the car's energy.
B) No, because only the drive force needs to be included.
C) No, because only external forces need to be included.
D) Yes, because every internal and external force must be included.
E) Yes, because of Newton's law of force pairs.
