Which sentences correctly uses parallel sructure

i think it would be c. or a. i recommend a if it's not a than it's c if it's not c than it's b your welcome : ) sorry if you get it wrong

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.  

faulty coordination occurs when the writer gives equal importance two different ideas (clauses) which in fact are not equivalent. in order to correct a misplaced clause or idea, the writer can place less important or emphatic ideas in a relative clause as in the previous sentence.  

well there are a bunch of different possibilities so your gonna have to be a bit more specific
