- C Inherited genetic disease that is always present from the moment of birth
- D Nutritional deficiency disease resulting from chronic poor diet
Correct answer: B. Non-communicable disease characterized by uncontrolled cell division and growth
Explanation: Cancer is a non-communicable disease (not spread from person to person) characterized by uncontrolled cell division, loss of normal growth controls, and ability to invade and spread (metastasis). It has genetic, environmental, and lifestyle causes.
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.
