The number of stylets in female mosquito is:

Correct option is C

The female mosquito has a highly specialized piercing and sucking type of mouthpart adapted for feeding on blood (hematophagy). The feeding apparatus consists of a proboscis that encloses six slender stylets, which are modified from parts of the insect’s original mouthparts.
�� Composition of the 6 Stylets in Female Mosquito:
1. Labrum – Forms the main food canal through which blood is sucked.
2. Hypopharynx – Lies beneath the labrum; it delivers saliva into the host to prevent blood clotting.
3. Mandibles (2) – Paired structures used to pierce the skin.
4. Maxillae (2) – Also paired, with serrated tips, they assist in cutting through skin and tissue.
All six stylets are enclosed within the labium, which folds backward during feeding and does not penetrate the skin.
