to be huge reservoirs of energy, possibly causing sea floor instability, and
to be huge reservoirs of energy, possibly causing sea floor instability, and even as
as huge reservoirs of energy, possibly causing sea floor instability, and
as huge reservoirs of energy, and the possible cause of sea floor instability,
as huge reservoirs of energy, as possible causes of sea floor instability, and even as

the answer is A, I chose E

Apparently E is better, don't u think so?
