Since the 1930's aircraft manufacturers have tried to build airplanes with fricitionless 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 perfectly so
I answered A, but here's my explanation why B is right.
A. Smooth shape doesn't make sense. Author means smooth surface. B. all words are in their correct forms, and so.. .that idiom's correctly used. C. you need adverb smoothly and perfectly. D. wordy E. having been is unnecessary here. _________________

A resumptive modifier picks up a word or phrase from a sentence that seems to be finished and then adds information and takes the reader into new territory of thought.
Example : 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 perfectly so
OA : B
Wings is required to unambiguously convey the meaning of the sentence. It is the wings that are shaped so perfectly and smoothly (adjective). Note how the subject "wings" is unambiguously and descriptively modified in B. Whereas A has ambiguity - it can modify "airplanes" instead of "wings".

afyl128, Resumtive modifier is the one which is introduced to remove any ambiguities, See in three of the options, themcan refer to manufacturers or wiings, but the resumptive modifier settles this down, now them can refer only to wings.
E being a evident wrong one B is the answer
