Vedclass · Answer

(C) The correct match is $C$. $1$. In $Arthropoda$, the body is typically divided into head, thorax, and abdomen (e.g., in $Insecta$), and respiration occurs through specialized structures like the trachea, book lungs, or gills. $2$. $Chordata$ (Option $A$) is incorrect because, while they have a notochord, many chordates (like mammals) have a common cloaca or separate openings, but the description is not a universal diagnostic feature for all. $3$. $Mollusca$ (Option $B$) is incorrect because while many are oviparous, the veliger larva is specific to certain classes like $Gastropoda$ and $Bivalvia$, not all mollusks. $4$. $Echinodermata$ (Option $D$) is incorrect because they typically exhibit external fertilization, not internal.
