Final Answer :
E
Explanation :
Arachnids have four pairs of walking legs attached to their cephalothorax and no antennae. Ticks and mites, although also arachnids, have a fused cephalothorax and abdomen and are therefore not the correct answer. Insects have three pairs of walking legs and one pair of antennae, crustaceans have ten or more legs and two pairs of antennae, and myriapods have many legs and one pair of antennae.
