Question

Which answer does not correct this run-on sentence? We need to leave by sunrise, make sure you pack before bedtime. A. We need to leave by sunrise. Make sure you pack before bedtime. B. We need to leave by sunrise; make sure you pack before bedtime. C. We need to leave by sunrise make sure you pack before bedtime. D. We need to leave by sunrise, so make sure you pack before bedtime.

Answer 1

C. We need to leave by sunrise make sure you pack before bedtime.

The sentence above would still be considered a run-on sentence (and makes no sense since there is no punctuation breaking "we need to leave by sunrise" from "make sure you pack before bedtime").
