annelids
vertebrates

Explanation:

• Annelids: These are segmented worms like earthworms. Scorpions, ticks, and mites are not segmented worms.
• Vertebrates: Vertebrates have a backbone. Scorpions, ticks, and mites lack a backbone.
• Echinoderms: Echinoderms (e.g., starfish, sea urchins) have a spiny - skinned endoskeleton and radial symmetry. Scorpions, ticks, and mites do not have these characteristics.
• Invertebrates: Invertebrates lack a backbone. Scorpions (arachnids), ticks, and mites (both arachnids as well) are all invertebrates.
