The correct answer is A. Malaria.
The question is a metaphor, comparing dogs to mosquitoes. Dogs can transmit rabies to humans, while mosquitoes can transmit malaria. Both rabies and malaria are serious diseases that can be fatal.
Malaria is a mosquito-borne infectious disease caused by protozoan parasites of the genus Plasmodium. The disease results in symptoms that typically include fever, chills, and anemia. In severe cases, it can cause coma, seizures, and death. Malaria is a major public health problem in many parts of the world, particularly in Africa, Asia, and Latin America.
Rabies is a viral disease that affects the central nervous system of mammals. It is usually transmitted to humans through the bite of an infected animal, most commonly a dog. Rabies is a fatal disease if not treated promptly.
The other options are incorrect because they do not accurately reflect the relationship between dogs and mosquitoes. Option B, “Sting,” is not a disease that is transmitted by mosquitoes. Option C, “Death,” is a possible outcome of both rabies and malaria, but it is not the only possible outcome. Option D, “Plague,” is a bacterial disease that is not transmitted by mosquitoes.
