Which of the following selections contains a run-on? If none of the selections contains a run-on, select "Correct."
(a) Everyone praised Matthew for his will power.
(b) He quit smoking five years ago, he still craves a cigarette from time to time.
(c) Addictions are hard to break
I think they are all correct sentences but I'm starting to question if (c) is a run-on.
