Solution
The correct option is A Auricularia
Echinoderms are the organisms which have radial symmetry. These are the organisms which have endoskeleton which is calcerous in nature and observed as spines on the body of the organism. The larvae of echinoderms pass through a number of stages. The stages of the larvae are represented by different names. Sea urchin has an echinopluteus larva while a brittle star has an ophiopluteus larva. A sea cucumber larva is an auricularia.
On the other hand, tornaria is the planktonic larvae of some species of Hemichordata. Amphiblastula is a free-living larva of certain sponges. While trochophore larva is the free-swimming larvae of marine annelids and most groups of molluscs.
Thus, the correct answer is option A.
