Final answer:
The group of words 'Wash your clothes.' is a correct sentence as it contains both a subject and verb, forming a complete thought.
Step-by-step explanation:
To determine whether the group of words "Wash your clothes." is a run-on sentence, a comma splice, a fragment, or a correct sentence, we need to analyze its components. This group of words contains a subject (implied 'you') and a verb ('wash'), forming a complete thought.
Therefore, it is a correct sentence. It is not a run-on sentence because it does not contain multiple independent clauses without proper punctuation. It is not a comma splice, as there is no inappropriate use of a comma joining two independent clauses. Lastly, it's not a fragment, because it contains both a subject and verb, providing a complete idea.
