Question

1. maria y luisa ____ puertorriqueñas.

soy
son
es

Explanation:

In Spanish, the verb "ser" (to be) has different conjugations. The subject "Maria y Luisa" is plural (two people), so we need the plural form of "ser". "Soy" is first - person singular ("I am"), "es" is third - person singular ("he/she/it is"), and "son" is third - person plural ("they are"), which matches the plural subject "Maria y Luisa".

Answer:

B. Son
