contraction of the cremaster muscle:
moves sperm through the ductus deferens.
propels sperm through the urethra.
pulls the testes closer to the body.
wrinkles the scrotal skin.

Explanation:

The cremaster muscle's contraction function: moving sperm through ductus deferens is done by peristalsis of ductus deferens; propelling sperm through urethra is by urethral smooth muscle and bulbospongiosus muscle; wrinkling scrotal skin is the dartos muscle's role. The cremaster muscle, when contracting, pulls the testes closer to the body (to regulate temperature, as testes need a slightly lower temp than body, and moving closer warms or protects).

Answer:

C. pulls the testes closer to the body.
