IMO E makes more sense than A but changes the intended meaning of the sentence.
In A it seems that the fact that they are huge reservoirs of energy causes the oceans instability while in E it seems that they cause this instability alone.
This is why I chose A, even if E makes more sense to me regarding the parallelism.
Is my reasoning so flawed?

The correct answer here should be E. "As + clause.." parallelism. Gas hydrates is being studied for 3 different purposes. 1. as huge reservoirs of Energy, 2. As possible cause of sea floor instability and 3. as significant contributors to global warming.
