- Option A: Head, Cephalothorax, and Abdomen - Cephalothorax is found in spiders and it is not considered an insect. So, this option is incorrect
- Option B: Cephalothorax, Midsection, and Abdomen - Cephalothoracic found in spiders which is not an insect and a middle section, especially the midriff of the human body. This option is incorrect.
- Option C: Head, Thorax and Abdomen - Insects have the main visible parts on the head are the large compound eyes, the antenna , and the mouthparts. Location of the thorax is in the middle region of the body, and it has the legs and wings There are three sections of the thorax: the prothorax, the mesothorax, and the metathorax. and The third part is the Abdomen. This option is correct.
- Option D: Head, Prothorax, and Metathorax - The insect thorax consists of three segments called the prothorax, mesothorax, and metathorax, which may be fused but are usually recognizable but here head is given so this option is incorrect.
Hence, the correct answer is, ‘(c) Head, Thorax, and Abdomen’.

NoteThe thorax is the midsection of the insect body.It helps in holding the legs and wings. Abdomen is the third division of the insect body that consists of nine or ten apparent segments. It contains reproductive and digestive organs. Head is the anterior part of the insect body and it has six segments which form a head capsule.
