Explanation:

Arthropods

Arthropoda is the largest phylum of animals within which, the class Insecta has the maximum number of species. Insects make up around 75% of the phylum Arthropoda. They occupy a variety of habitats and can crawly, fly, jump and swim. Most of the lay eggs in protected places and only a few species show parental care. They sometimes protect themselves with venom and use camouflage to protect themselves from predators or to attack prey.
So, the correct answer is 'Insects'.
