Final answer:
The phylum Arthropoda is divided into the superclasses of Myriapoda (millipedes and centipedes), Hexapoda (insects), Crustacea (crabs, lobsters, crayfish), and Chelicerata (spiders, scorpions, mites).
Step-by-step explanation:
The phylum Arthropoda encompasses a vast array of organisms that have successfully adapted to live in different environments, including land, water, and air. Arthropods are characterized by their jointed appendages, segmented bodies, and hard exoskeletons made of chitin. The phylum is divided into several superclasses, which are further subdivided into various taxa based on characteristics such as mouthparts, number of appendages, and body subdivisions.
The phylum Arthropoda is divided into the superclasses of Myriapoda (millipedes and centipedes), Hexapoda (insects), Crustacea (crabs, lobsters, crayfish), and Chelicerata (spiders, scorpions, mites).
Answer (a) Myriapoda, Hexapoda, Crustacea, and Chelicerata is the correct division of superclasses that the phylum Arthropoda can be divided into as these groups cover the main diversity within the phylum.
