explanation: the last part of the sentence “she will be here soon” sounds out of place. in order to make it flow, it would need a conjunction such as, because. therefore this makes it the answer.
D) we should clean the house before your mother comes home she will be here soon
A run-on sentence occurs when two or more independent clauses (also known as complete sentences) are connected improperly. Example: I love to write papers I would write one every day if I had the time.
