Question

tú ___ muy inteligente. options: es, sois, eres, soy

Explanation:

In Spanish, the subject "tú" (you, singular informal) requires the corresponding form of the verb "ser" (to be). The correct conjugation of "ser" for "tú" is "eres". Let's analyze the options: "es" is for "él/ella/usted" (he/she/you formal), "sois" is for "vosotros/vosotras" (you all, informal in Spain), "soy" is for "yo" (I). So the correct verb form to fill in the blank is "eres".

Answer:

eres (the option with "eres" in the green box)
