Spiders and scorpions belong to which arthropod class?

Explanation:
Spiders and scorpions belong to arachnids, a group of arthropods defined by having eight legs, two main body segments (a cephalothorax and an abdomen), and mouthparts called chelicerae and pedipalps. They also lack antennae and wings, which helps distinguish them from other arthropod groups. Insects have six legs and three body parts, crustaceans typically have paired antennae and various aquatic-adapted limbs, and “decomposers” isn’t a formal taxonomic class. The combination of eight legs, two body regions, and no antennae makes arachnids the best fit for spiders and scorpions.
