The correct option is D All of the above

Arthropods have jointed appendages and include aquatic crustaceans, arachnids, aquatic chelicerates and insects. Different arthropods use different organs for respiration. For example, aquatic crustaceans such as crabs, lobsters, prawns, shrimps, have gills. Aquatic chelicerates such as horseshoe crabs use book gills. Arachnids such as spiders have book lungs. Insects use a series of tubes or trachea that branch throughout the body (tracheal system).
