Answer: Option D
Solution(By Examveda Team)
Protrusible hollow stylet types of mouth parts are possessed by plant parasitic nematodes.At the head of a plant-parasitic nematode is a hollow mouth spear (like a hypodermic needle) called a stylet. The mouth cavity is armed with a protrusible stylet in the form of a hollow needle, which is used to puncture plants to obtain liquid food.
The nematode uses this stylet to puncture plant cells, withdraw food, and also to secrete protein and metabolites that aid the nematode in parasitizing the plant.
