Marco y Juan: Sí, ellos son ___________.
mis abuelos
su padre
sus padres
nuestros abuelos

Answer 1

Si,ellos son nuestros abuleos

Answer 2

nuestros abuelos

Step-by-step explanation:

The grammar gives you a clue to the answer. Since it's Marco and Juan answering a direct question, the answer must be in first person plural. "Nuestros" is the possessive for first person plural. Translation wise, the question is "Are they your mother's parents?" and the answer "Yes, they are our grandparents"
