Identify the sentence that uses incorrect parallel structure
a. mom is watching tv in the living room, and dad is mowing the backyard
b. concerned citizen can write letters, show up at the polls, and will be wearing pins that say, “honestly now.”
c. i usually like to unwind with a book or fall asleep in my beach chair.
d. strengthens core muscles, icing regularly, and visiting the chiropractor can all reduce back pain

B. Concerned citizens can write letters, show up at the polls, and will be wearing pins that say, "Honesty Now."

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.
