Mettez à la forme du verbe qui convient Qu'est-ce que vous (choisir)?

In French, verbs need to be conjugated to agree with the subject in both number (singular/plural) and person (first, second, third). Here, we must choose the correct form of the verb "choisir" in the context of the sentence with the subject "vous".

The subject "vous" can be used in two situations:

• When addressing one individual formally.
• When addressing more than one person (plural).

In both cases, the appropriate conjugation of the verb "choisir" for "vous" is "choisissez".

Therefore, the correct sentence is: "Qu'est-ce que vous choisissez ?"

This conjugation is in the present tense, and it relates the action directly to the ongoing conversation or moment. Thus, when you ask someone, "Qu'est-ce que vous choisissez ?", it translates to "What are you choosing?" or "What do you choose?" in English, addressing either a single person formally or multiple people.
