IMHO, it's E.

The main reason I think it's not A is because it seems that the 'that' refers to the testing and not the jet engine. Or maybe I'm misreading it?

B. tested that could eventually have the capability of propelling aircraft anywhere in

C. tested, eventually able to propel aircraft anywhere in the world within two hours,
or helping (if you remove the sentence within the commas, it doesn’t make sense which it should)
28
D. tested, and it eventually could propel aircraft anywhere in the world within two
hours or helping (not parallel – propel vs. helping)
E. tested, and it could eventually have the capability to propel aircraft anywhere in
the world within two hours or help (wordy)
