Patients who are on chemotherapy drugs often lose their hair. Which best explains why this happens?

Chemotherapy drugs target cells that divide rapidly, which includes many cancer cells.

Choice A correctly describes this effect on healthy cells; the other choices incorrectly attribute hair loss to antagonism, agonism, or activation of a prodrug in hair cells.
