Vedclass · Answer

(C) Statement $(A)$ is correct: The infective stage of $Ascaris \; lumbricoides$ is the embryonated egg containing the second-stage juvenile ($L_2$ larva).Statement $(B)$ is correct: Fertilised eggs are passed out of the host's body along with the faeces. At this stage, the egg contains an unsegmented ovum.Statement $(C)$ is incorrect: In $Ascaris$, the $1^{st}$ moult occurs within the egg in the soil. The $2^{nd}$ moult also occurs in the soil (making it infective). The $3^{rd}$ and $4^{th}$ moults occur within the host's body (specifically in the lungs and intestine).Statement $(D)$ is correct: The adult $Ascaris$ worm resides in the small intestine of the human host.Therefore, statements $(A), (B),$ and $(D)$ are correct.
