Correct answer: B. Macrophagous
- A. Fluid
- B. Macrophagous

Explanation
Hydra captures relatively large solid prey with its tentacles and digests it in the gastrovascular cavity, so it is a macrophagous feeder. The likely mistake is fluid feeding, which involves taking in dissolved nutrients rather than whole prey.
