IMO A

THAT COULD ....PROPEL .....OR HELP (PARALLEL) So only A and E

that refers to engine so sounds better....engine that ....

E is my pick. Usage of "that" makes it feel like "tested" is the one that is helping propel the aircraft, but it's the jet engine that will help propel.

I am totally confused between A and E.
According to me A is correct and "that" is correctly used.
Also in E 'it' might refer to research and development which is wrong.
Can someone plz provide better explaination
