(A) like a spinning figure skater whose speed increases when her arms are drawn in - Comparing verb (Speed up) with noun (spinning figure skater). Incorrect

(B) like the increased speed of a figure skater when her arms are drawn in - we need to compare something, wich is spped up the rotation with something, spped up some other rotation. Therefore, this is wrong.

(C) like a figure skater who increases speed while spinning with her arms drawn in -- Same as A

(D) just as a spinning figure skater who increases speed by drawing in her arms -- Same as A

(E) just as a spinning figure skater increases speed by drawing in her arms -- Correct 'the build up speed up ratiotion just as a spinning figure skater speed up' proper comparison. Therefore, correct
