correct answer is: option b (Phylum - Cnidaria)
Explanation: Jellyfish belong to the phylum Cnidaria. This phylum is characterized by animals with radial symmetry, specialized stinging cells called cnidocytes (used for capturing prey), and a simple body plan with a gastrovascular cavity.
- Option a: Protozoa are single-celled eukaryotic microorganisms. Jellyfish are multicellular animals.
- Option b: Cnidaria is the correct phylum for jellyfish as they exhibit the defining characteristics of this group.
- Option c: Porifera includes sponges, which are characterized by their porous bodies and lack of true tissues.
- Option d: Ctenophora includes comb jellies, which are similar to jellyfish but belong to a different phylum and use cilia for locomotion instead of jet propulsion.
