ANS: A
The cremasteric reflex is a superficial (i.e., close to the skin's surface) reflex observed in males. This reflex is elicited by lightly stroking the superior and medial (inner) part of the thigh regardless of the direction of stroke. The normal response is an immediate contraction of the cremaster muscle that pulls up the testes on the side stroked (and only on that side).
