Correct answer: C. Fungus
Explanation: Ringworm (tinea) is a fungal infection caused by dermatophytes (Microsporum, Trichophyton, Epidermophyton). Despite its name, no worm is involved. It causes ring-shaped, itchy skin lesions. Treatment: antifungal cream.
The Plasmodium parasite needs both hosts: the female Anopheles mosquito injects sporozoites while biting (infecting the human liver and RBCs, causing the malaria fever cycle), then picks up gametocytes from an infected person's blood, completing the parasite's sexual stage inside the mosquito.
