How many body regions does an adult insect have?

Explanation:
Insects have three main body regions called tagmata: the head, the thorax, and the abdomen. The head houses sensory organs and mouthparts, the thorax bears the legs (and usually wings), and the abdomen contains much of the digestive and reproductive systems. Because of this three-part organization, an adult insect has three body regions. Options proposing two, four, or five regions don’t fit the standard insect body plan, since there aren’t additional distinct regions that are recognized as separate tagmata in adult insects.
