What is a common feature of all insects?

• A. They have more than three body segments
• B. They possess wings
• C. They have three body segments and six legs
• D. They are capable of flight

Answer: (C)

Insects are characterized by a specific body structure that includes three distinct segments: the head, thorax, and abdomen. This segmentation is a defining feature of the class Insecta. Additionally, all insects have six legs, which differentiates them from other arthropods. The combination of these three body segments and six legs is a universal characteristic among all insects, making this option correct. While some insects possess wings and are capable of flight, not all insects share these features. For instance, ants and termites are examples of insects that do not have wings in their adult form, yet they still fit the classification of insects due to their three body segments and six legs. Thus, focusing on the basic structure highlights the defining features that categorize a creature as an insect.
