C it is.
The underlying physical principles that control the midair gyrations of divers and gymnasts are the same as the body orientation controlling astronauts in a weightless environment.
A. as the body orientation controlling - comparison missing
B. as the body orientation which controls - comparison missing
C. as those (physical principles ) controlling the body orientation of
D. ones to control the body orientation of - awkward
E. ones used in controlling the body orientation of - wordy
I replace one or ones with the proper referent. Here the referent is principles.
So D become --> principles to control the body orientation of
& E become --> principles used in controlling the body orientation of
whereas C become--> as principles controlling the body orientation of
I agree D doesn't fit in but E after replacing the referrant(principles) looks better and clearer than C to me even though C looks slimmer.
If you know what you're worth, then go out and get what you're worth. But you gotta be willing to take the hits, and not pointing fingers saying you ain't where you wanna be because of anybody! Cowards do that and You're better than that!
The path is long, but self-surrender makes it short; the way is difficult, but perfect trust makes it easy.
Fire the final bullet only when you are constantly hitting the Bull's eye, till then KEEP PRACTICING.
Failure establishes only this, that our determination to succeed was not strong enough.
Getting defeated is just a temporary notion, giving it up is what makes it permanent.
Press +1 Kudos, if you think my post gave u a tiny tip.
