The answer is E. Rays and Skates belong to the superorder Batoidea. Batoids have developed heavy, rounded teeth for crushing the shells of bottom-dwelling species such as snails, clams, oysters, crustaceans, and some fish, depending on the species.

I am not sure about this subject, but would incline towards (e).
However, saw recently on TV that some rays eat squid (not the large ones). Actual film of them doing it.
So the (e) answer is not exhaustive.
All weighed together, looks more like (e).
Hope I'm not wrong. Wish I knew something useful about Skates.
