Answer
Blue whale
The correct answer is Blue whale — Therefore the animal that belongs to phylum Chordata is the Blue whale.
Step-by-step solution
- Recall that phylum Chordata includes animals that possess a dorsal nerve cord, a notochord, pharyngeal slits, and a post‑anal tail during some stage of development.
- Examine each option: Anemone is a cnidarian; Honeybee is an insect; Blue whale is a mammal, thus a vertebrate and a chordate; Earthworm is an annelid.
- Therefore the animal that belongs to phylum Chordata is the Blue whale.
Common mistake: Choosing an insect (e.g., honeybee) because it has wings, ignoring the defining features of Chordata
