Answer: Option C

Solution(By Examveda Team)

The nematodes lack organs for Circulation and Respiration.
While nematodes have digestive, reproductive, nervous, and excretory systems, they do not have discrete circulatory or respiratory systems.
Nematodes use chemosensory and mechanosensory neurons embedded in the cuticle to orient and respond to a wide range of environmental stimuli.
