The dermis is located beneath the epidermis and contains connective tissue, nerves, and blood vessels. The hypodermis is the deepest layer of the skin, consisting of fat and connective tissue.

Correct answer: A

Rationale: The correct answer is A, "Lunulae." The moon-shaped white structures at the base of fingernails are called lunulae. These are most visible on the thumb and are the visible part of the nail matrix. The lunulae appear white because the nail matrix underneath is not visible due to its thickness. Cuticle (B) refers to the thin layer of skin at the base of the nail, hyponychium (C) is the skin located under the free edge of the nail, and matrix (D) is the tissue at the base of the nail where growth occurs. Therefore, the correct term for the moon-shaped white structures is lunulae.
