Since your asking what goes after "Nosotros" it would make more sense for "somos". Answer- "De Argentina Nosotros somos."

Explanation:
In Spanish, we can conjugate for many different pronouns.
- Yo: I
- Tú: You
- Él/ella/usted: he, she, you (formal)
- Nosotros: We
- Vosotros: You all (informal)
- Ellos/ellas/ustedes: they, you all (formal)
Let's look at the sentence we are given:
Juan y yo ____ la clase de español todos los días
- Juan y yo translates to Juan and I, which also means we. Refer to the pronouns above and see that we is nosotros.
- Tener conjugated for nosotros is tenemos.
Juan y yo <u>tenemos </u>la clase de español todos los días (Juan and I have Spanish class every day)
