Vedclass · Answer

(B) Let's analyze each option:$A$. $Ascaris$ belongs to the phylum Aschelminthes (Nematoda). It has a non-segmented (pseudocoelomate) body,not a segmented one. Thus,this is incorrect.$B$. $Salamandra$ belongs to the class Amphibia. Amphibians have a tympanum representing the ear and typically undergo external fertilization. This is a correct match.$C$. $Pteropus$ (flying fox) belongs to the class Mammalia. While they have hair on their skin,they are viviparous (give birth to young ones),not oviparous. Thus,this is incorrect.$D$. $Obelia$ belongs to the phylum Coelenterata (Cnidaria). While they possess cnidoblasts,they exhibit tissue-level organization,not organ-level organization. Thus,this is incorrect.
