Which muscle elevates the lower lip and wrinkles the skin of the chin?

Explanation:
The muscle that elevates the lower lip and wrinkles the skin of the chin is the mentalis. Located at the tip of the chin, its fibers pull upward on the chin skin and push the lower lip outward, producing a pout and forming vertical wrinkles in the chin area. The other muscles have different roles: the platysma tenses neck skin and can pull the corners of the mouth downward, not wrinkle the chin; the depressor labii inferioris depresses the lower lip; and the orbicularis oculi closes the eyelids.
