Which three body parts make up an adult mosquito?

An adult mosquito is composed of three primary body parts: the head, thorax, and abdomen. The head contains the mosquito's sensory organs and mouthparts, which include the proboscis used for feeding. The thorax is responsible for locomotion and houses the wings and legs, allowing the mosquito to fly and move effectively. Finally, the abdomen contains the digestive and reproductive systems. This structural organization is crucial for the mosquito's survival and its ability to fulfill its roles in the ecosystem, such as pollination and serving as a food source for other animals.

In this context, while the other options mention certain body parts, they do not accurately represent the complete tripartite body structure defined for mosquitoes. For instance, focusing on other components like wings or legs without acknowledging the head and abdomen misses the fundamental categorization of mosquito anatomy.
