Answer: Option C

The maxillary stylets in case of Thysanoptera are mostly Lacinia.
Thrips (order Thysanoptera) are minute, slender insects with fringed wings and unique asymmetrical mouthparts.
Thrips have asymmetrical mouthparts unique to the group. Unlike the Hemiptera (true bugs), the right mandible of thrips is reduced and vestigial – and in some species completely absent.
The left mandible is used briefly to cut into the food plant; saliva is injected and the maxillary stylets, which form a tube, are then inserted and the semi-digested food is pumped from ruptured cells.
