Cutaneous larval migrans is a skin condition caused by the migration of certain larvae beneath the skin, leading to a characteristic rash. The correct choice is hookworm, which is known to penetrate the skin. When humans come into contact with contaminated soil or sand that contains hookworm larvae, these larvae can enter the skin and migrate through the superficial layers, causing the telltale serpentine marks associated with cutaneous larval migrans.

The other parasites listed do not typically cause this specific skin condition. Roundworms primarily reside in the intestines and are less likely to penetrate the skin in humans. Whipworms are also intestinal parasites that do not cause skin manifestations in humans. Heartworms, while a serious concern in canines and felines, are transmitted through mosquito bites and do not cause cutaneous larval migrans. Therefore, hookworms are uniquely associated with the skin condition due to their life cycle and method of transmission.
