The correct option is A Digestion of food
Phylum coelenterata (cnidaria) has specialised structure called cnidoblasts or cnidocytes which contain the stinging capsules or nematocytes. Cnidoblasts are used for anchorage, defense and for the capture of prey. Digestion of food in cnidaria is carried out in gastro-vascular cavity with a single opening called hypostome.
