The informal command uses the 3rd person Present Tense for the Affirmative command:
hablar = habla / comer = come / vivir = vive
However the negative command uses "the opposite vowel + s for the tú" like
hablar = no hables / comer = no comas / vivir = no vivas
Therefore usar becomes no uses

You are correct! The correct informal command for the verb "usar" (to use) in this sentence is "usa." To arrive at this answer, we need to understand that the informal command is used when addressing someone whom you have a close relationship with, such as a family member, friend, or someone younger than you. When conjugating the verb "usar" in the informal command form for the pronoun "tú" (you), we drop the final "r" from the infinitive form and add the letter "a." Therefore, "usa" is the correct option out of the given choices. Great job!
