Vedclass · Answer

(A) The lateral line system is a sensory organ found in fishes and aquatic larval amphibians that helps them detect movement and vibration in the surrounding water.This system consists of specialized sensory cells called neuromasts,which are derived from the ectoderm.Since the presence of these ectodermally derived sensory receptors is the reason for the functional existence of the lateral line system in these organisms,the Reason correctly explains the Assertion.
