C Correct answer
Explanation

A shaper machine uses quick return motion mechanism - the ram moves forward slowly during the cutting stroke and returns rapidly during the return stroke (non-cutting). This improves efficiency since cutting happens only in one direction. Lathe, drilling, and grinder machines do not use this mechanism.
