The correct answer is (c), roundworm. Ascaris lumbricoides is a parasitic roundworm that infects humans. It is the most common human helminth infection worldwide, with an estimated 1.2 billion people infected. The worms live in the small intestine and can cause a variety of symptoms, including abdominal pain, diarrhea, and malnutrition. In severe cases, they can block the intestines or migrate to other organs, such as the lungs.

Hookworms are a type of parasitic roundworm that can infect humans. They are small, thin worms that live in the small intestine. They attach to the intestinal wall and suck blood, which can cause anemia and malnutrition.
