C Correct answer
Explanation

In DC generators, the generated emf and armature current flow in the same direction - both leave the positive terminal during generation. This is the fundamental principle of generator operation. In motors, the emf (back emf) opposes the current flow. Series and shunt motors consume electrical power, so their emf opposes current.
