Fill in the blank with a possessive pronoun that best completes the sentence. you must remember to clean room before you go to the movies. a) the b) you c) your d) yours

You must remember to clean your room before you go to the movies.

C) Is the only option that makes sense when sounding the sentence out aloud, and is possessive. "The" is not possessive, "Clean you room" does not sound grammatical, and "Clean yours room" also is not grammatical. Hopefully this helps!
