Answer: Option A

Solution(By Examveda Team)

In nematode, Chitin is present only in Egg shell.
Chitin is found in the eggshells of many free-living and parasitic species, and in the modified eggshell or sheath that surrounds first-stage larvae of filarial nematode parasites.
Eggshell chitin synthesis is initiated at fertilization, and chitin is deposited before the zygote exits the spermathecal.
