choose the best answer.\n¿cuál es el pasatiempo favorito de tu sobrino?\no el pasatiempo favorito de mi…

Brief Explanations:

In Spanish, the correct way to say "My nephew's favorite hobby is soccer" is "El pasatiempo favorito de mi sobrino es el fútbol." The verb "ser" (to be) in the present - indicative form "es" is used to express identity or definition. The other options have incorrect verb forms or conjugations. "Ser el fútbol" uses an incorrect non - conjugated form of "ser", "está el fútbol" uses the verb "estar" which is for location or temporary states, and "estoy el fútbol" uses the first - person singular form of "estar" which is completely wrong in this context.

Answer:

El pasatiempo favorito de mi sobrino es el fútbol.
