Choose the correct translation: you (formal)

The correct answer is Usted/Ustedes.

Explanation:

Unlike English, where the pronoun you can be used for normal or informal conversation, in Spanish there are two different pronouns for each of these situations.

For informal situations we use Tú, and for formal situations we use Usted (Ustedes for the plural).

Next I will write all the pronouns that exist in Spanish:

persona   singular              plural

1ª             yo                    nosotros,   nosotras

2ª             tú                    vosotros,   vosotras

3ª             él, ella, Ud.,           ellos, ellas, Uds.
