Vedclass · Answer

(C) The correct answer is $C$. In cockroaches,the mandibles are a pair of heavily sclerotized,triangular structures with jagged teeth-like edges. These structures are operated by powerful abductor and adductor muscles,which move them in a horizontal plane. This movement allows the cockroach to effectively cut and chew food particles that are positioned between the mandibles by the first maxillae.
