Explanation:

Question 7

The lunula (the white, half - moon - shaped area at the base of the nail) has a lighter color that reflects the true color of the nail matrix. The nail plate is the visible part of the nail, the nail bed is the tissue under the nail plate, and nail folds are the skin folds around the nail. So the correct option is related to the lunula.

The hair structure consists of different layers. The hair cuticle is the outermost layer, made of overlapping scales. The hair follicle is the structure that produces the hair, the hair cortex is the middle layer, and the hair medulla is the innermost (sometimes absent) layer.

A pimple or abscess is a localized infection, meaning it is confined to a specific area. A blood disease affects the blood, a general infection spreads throughout the body, and a daughter cell is a cell resulting from cell division, not related to infections.

Answer:

c. lunula
