Hint: Phylum arthropoda has the most abundant and successful animals of kingdom Animalia. Phylum arthropods involved insects, spiders, crabs, centipedes, lobsters, mites, and millipedes. The word Arthropod means jointed appendages (“Arthro means jointed” and “poda means appendages”).

Complete answer:Depending upon different characteristics all living organisms are classified into six kingdom classification which also tells us how these organisms are related to each other. Arthropod comes under the phylum Arthropoda which belongs to the kingdom Animalia. Phylum arthropod is the largest phylum of kingdom Animalia and contains almost 65 to 70 percent of total animal species on the planet. They have certain features that make them most successful of all animal species. This larva goes through many stages to become an adult organism, this process is called metamorphosis. Arthropods are divided into 4 classes:
Class Crustacea: Members of this class have many legs and have 2 body segments such as Prawns.
Class Myriapod: Members of this class have many pairs of legs and have 3 body segments such as Centipede.
Class Insecta: Members have 3 pairs of legs and 3 body segments such as housefly, and silverfish.
Class Arachnida: Members have 4 pairs of legs and 2 body segments such as scorpion.
Hence, the correct option is option B-Silverfish.

Additional Information:The body of arthropods has three sections: Head, Thorax, and Abdomen. They have segmented bodies with a pair of jointed appendages to every segment. Some members of arthropods like millipedes can have up to 100 legs. Sometimes the head and thorax of their fuse together to form a cephalothorax. They have an exoskeleton made up of chitin, a polysaccharide with an additional nitrogen group. They are coelomates (organisms with a body cavity) with an open blood circulatory system (Blood does not flow through vessels). Most arthropods are oviparous (egg-laying organisms) except a few like scorpions and spiders give birth to young ones (direct development).

Note: During development in arthropods, only internal growth takes place hence the organism has to shed its exoskeleton from time to time. The exoskeleton of arthropods is nonliving and the process of shedding exoskeleton is known as Moulting or Ecdysis. After moulting, they can regrow their exoskeleton. In this period, most of the predators target arthropods as it is easy to kill organisms without the exoskeleton.
