"proved itself" in C and D is wrong. Canon is not proving itself

"as a demonstration of" in B is wordy and awkward

among A and E, "in demonstrating" is better than "to demonstrate"

So E.

"Between" A and E.
I go with E.

A>> only when the cannon is "shooting" it is demonstrating...not the intended meaning
