Solution

The correct option is D Both A and B
Cnidarian animals are characterised with cnidoblasts or cnidocytes (which contain the stinging capsules or nematocysts) present on the tentacles and the body. Cnidoblasts are used for anchorage, defense and for the capture of prey. Nematoblasts of cnidoblasts are sensory in nature and they contain nematocyst apparatus.
Therefore, the correct answer is option C.
