a whitehead is also called a _____.
a sebaceous cyst
b nodule
c keratoma
d closed comedo

Explanation:

In dermatology (a subfield of Medicine and Health, part of Natural Science), a whitehead is a type of acne lesion. A closed comedo (option d) is the correct term for a whitehead, as it's a plug of sebum and dead skin cells trapped in a hair follicle with the opening closed, appearing as a white bump. A sebaceous cyst is a different, usually larger, encapsulated lesion. A nodule is a solid, larger acne lesion, and a keratoma is a growth of keratin, not related to whiteheads.

Answer:

d. closed comedo
