First, when we report the results of a study, theses, hypothesis, findings, and the like, it is customary to introduce the effects in a subordinate clause introduced by 'that.'

Einstein's theory proposes that all the cosmic bodies bound by the 'Relativity' theory
His study proves that marine fish does not grow well in fresh water

However, we can also drop the subordinate conjunction 'that; but the structure will then involve an infinitive or a gerund
Einstein's theory proposes all the cosmic bodies to be bound by the 'Relativity' theory
His study proves marine fish not (to grow well/growing well) in fresh water.
That is the reason that we can drop A and B.

Second, when we write a simple sentence containing one IC followed by a modifier, then we should never use a co-ordinate conjunction such as 'and' or 'but.' Else, the sentence will turn unparallel. C is gone.

D is unidiomatic, as Chetan has pointed out, leaving E as the only reasonable choice

My choice is E.
