Solution
The correct option is D Arthropoda
The phylum Arthropoda (“jointed foot”) has the largest number of species. In fact, about 85 percent of known species are arthropods and insects alone make up about 75 percent of known species. Other arthropods include the centipedes and millipedes; the arachnids (spiders, scorpions, ticks, mites); and the crustaceans (barnacles, crabs, crayfish, lobsters, shrimp, water fleas). Obviously, the arthropod body plan has been highly successful. The members of this phylum live on land, in freshwater, and in saltwater. They can walk, fly, burrow and swim. This is the only invertebrate group with jointed appendages (legs, feet, and antennae).
