Which statement accurately describes arachnids?

Arachnids are a class of joint-legged invertebrates within the phylum Arthropoda, and the defining characteristics of this class include having two distinct body segments, which are the cephalothorax and the abdomen. They also possess eight legs, which distinguishes them from insects that have six legs. Notably, arachnids do not have wings or antennae, setting them apart from other arthropods like insects. This anatomy allows arachnids, such as spiders, scorpions, and ticks, to exhibit a wide range of behaviors and adaptations necessary for their lifestyle. The accurate description aligns with these biological traits, reinforcing the crucial characteristics that define arachnids.
