The correct answer is D. Striae are a form of dermal stretching of the dermis. It often causes stretch marks or scarring. These marks are often associated with rapid weight changes such as gain or loss. An example might be in pregnancy or endogenous or exogenous corticosteroids use. Striae are not caused by a loss of hair follicles, too many fibers in the hypodermis, or pimples.
