Question

you are (estar, formal)
estar
ustedes son
usted está
ustedes están

Explanation:

The problem is about conjugating the verb "estar" in the formal "you" (singular or plural) form. For the formal singular "you" (Usted), the conjugation of "estar" is "está". For formal plural "you" (Ustedes), it's "están". But the question "You are (estar, formal)" – if it's formal singular (Usted), the correct form is "Usted está". Let's check the options: the purple box has "Usted está", which matches the formal singular "you" conjugation of "estar". The other options: "Ustedes son" uses "ser" not "estar", "Ustedes están" is plural formal, but the question's "you" could be singular formal. So the correct one is the purple box: Usted está.

Answer:

Usted está
