Vedclass · Answer

(A) The prostomium is a small fleshy lobe that overhangs the mouth of an earthworm.
Statement $(a)$ is correct as it acts as a covering for the mouth.
Statement $(b)$ is correct as it is used as a wedge to force open cracks in the soil.
Statement $(c)$ is correct as the prostomium is sensory in function.
Statement $(d)$ is incorrect because the first body segment of the earthworm is the peristomium (or buccal segment),not the prostomium. The prostomium is a pre-oral lobe located anterior to the first segment.
Therefore,statements $(a), (b)$ and $(c)$ are correct.
