Since the 1930's aircraft manufacturers have tried to
build airplanes with frictionless wings, shaped so smoothly and perfectly that the air passing over
them would not become turbulent.
(A) wings, shaped so smoothly and perfectly
(B) wings, wings so smooth and so perfectly shaped
(C) wings that are shaped so smooth and perfect
(D) wings, shaped in such a smooth and perfect manner
(E) wings, wings having been shaped smoothly and
smooth can't modify shaped. it is the characteristic of the wing. so do perfectly(adverb) shaped.
Comma usage led to an incorrect referent. SHAPED : does it refer to the airplanes with smooth wings or the wings themselves. Using Resumative modifier (repeated usage of wings) clarifies what is being modified.
