Which of the following components are part of the basic sections that make up the mouthparts of an insect's head, which is a capsule housing the brain, eyes, antennae, and typically ectognathous mouthparts?

Explanation

The insect head contains several fundamental mouthpart sections: the labrum (upper lip) whose ventral surface forms the epipharynx; the hypopharynx, a tongue-like organ, and the mandibles (jaws); as well as the paired maxillae and the labium (lower lip). Therefore, all these components collectively constitute the basic mouthpart structure.
