Question

fill in the blank with the missing possessive adjective.
______ (él) teléfono es nuevo.
mi
su
tu
nuestro

Explanation:

The subject here is "él" (he), so we need the possessive adjective that corresponds to "he" in Spanish. "Su" is the possessive adjective used for "él" (his), "ella" (her), "usted" (your, formal). "Mi" is for "yo" (my), "Tu" (with a lowercase 'u' here, but should be "Tu" for "tú" (your, informal)) and "Nuestro" is for "nosotros" (our). So the correct possessive adjective for "él" is "Su".

Answer:

B. Su
