Vedclass · Answer

(D) The correct answer is $D$. $Sea$ $squirt$ (also known as $Herdmania$) belongs to the subphylum $Urochordata$ (or $Tunicata$). In $Urochordates$,the notochord is present only in the larval tail and is replaced or lost in the adult stage. Since they do not possess a vertebral column,they are classified as protochordates (invertebrate chordates) rather than vertebrates.
