Which arthropod class has four pairs of legs and includes spiders, scorpions, ticks, and mites?

Explanation:
Arachnids are the group defined by having eight legs (four pairs) and include spiders, scorpions, ticks, and mites. Insects, by contrast, have six legs and typically three main body segments with antennae. Crustaceans vary a lot but often have more than six legs and two antennae, and “decomposers” isn’t a taxonomic class. So the features that line up with all the examples—spiders, scorpions, ticks, and mites—point to arachnids. They also use specialized mouthparts called chelicerae and usually lack wings.
