The run-on sentence , in this case is option C "Lindsey was exhausted she had not gotten enough sleep for weeks". The sentence does not have a comma (,) to separate the clauses, they are not properly connected. however, they make sense in isolation. "Lindsey was exhausted" and "she had not gotten enough sleep for weeks" . They are just put together.
