GMAT Sentence Correction (SC) | Re: Thelonious Monk, who was a jazz pianist and composer,

Pl. note the word ‘both’ is a wrong diction in the context. There is only one style namely the stride-piano tradition of Willie (The Lion) Smith and Duke Ellington in which Monk’s jazz was rooted and not two styles as the text wants to make out by deviously citing two musicians. Therefore, all choices that use the word ‘both’ namely A, B and E are out of the race. Between C and D, C is a fragment. D is the correct answer.
