The correct choice is (a) Pisaster
 
For explanation I would say: Pisater is an important predator in the rocky intertidal communities of the American Pacific Coast that feeds on barnacles, planktons, echinoids, etc. Predation is an interaction in which an organism (predator) is benefited by killing another organism (prey).
