Correct Answer: Ancylostoma - Pinworm

Solution : The correct option is Ancylostoma - Pinworm.

Ancylostoma is a genus of hookworms that can infect humans and other animals. These parasites typically attach to the intestinal wall and feed on blood, leading to symptoms such as anaemia and fatigue.

Pinworms, on the other hand, belong to the genus Enterobius. They are small, white, thread-like worms that commonly infect the human intestines, especially in children. The condition caused by pinworm infection is known as enterobiasis or pinworm infestation.
