Verified by Toppr

Fruit flies have sucking and sponging mouthparts. Fruit flies have maxillae, elongate blades that overlie a groove in the labium and form a tubular channel for sucking liquids. Sponging mouthparts appear as a conical process with sponge like lobes at the end. These type of mouthparts are modified to lap up liquids. After sensing the presence of food, the insects secrete viscous liquid as saliva. This saliva and the atmospheric water helps the sugar to get dissolved and get converted in the liquid form. The liquid is then soaked and sucked with the help of the mouth parts.
Thus, the correct answer is option C.
