E)none of the choices is correct.

Accepted Answer

Digestion in hydra is both extracellular and intracellular. The Hydra uses tentacles to capture and trap small aquatic animals, such as tiny crustaceans and rotifers, which it then extracellularly digests in the digestive cavity. The cells lining the cavity then engulf and break down the small food particles intracellularly.
