Solution
The correct option is C Decapods
The decapods are an order of Crustaceans within the class Malacostraca, such as crayfish, crabs, lobsters, prawns and shrimp. As the name Decapoda implies, all decapods have ten legs, in the form of five pairs of thoracic appendages on the last five thoracic segments. The front three pairs function as mouthparts and are generally referred to as maxillipeds; the remainder are pereiopods. Most decapods are scavengers. Therefore, the correct answer is option C.
