Solution
The correct option is BAmphilina Deuterostomes are groups of animals that have true body cavities, in which the anus develops from the first opening in the embryo and the mouth develops later. All chordates are deuterostomes.
Ambystomaare a group of salamanders endemic to North America.
Anguillais a species of eel, a snake-like, catadromous fish.
Amphiuma is a genus of aquatic salamanders. Therefore they all are deuterostomes.
Amphilina are platyhelminthes, which are parasitic in the body cavity of sturgeons. Therefore Amphilina is not a deuterostome. Hence, option B is correct.
