Respuesta :
The answer is D somos. The sentence says we are mexicans. Somos is the correct conjugation of the verb ser.
Right answer: somos
The spanish verb ser (to be) is conjugated with each subject pronoun, as follows:
1st person singular: Yo soy
2nd person singular: Tú eres
3rd person singular: Él/Ella/eso/esa es
1st person plural: Nosotros somos
2nd person plural: Ustedes (In latinAmerica) son
2nd person plural: Vosotros (In Spain) sois
3rd person plural: Ellos/Ellas son
Now, this sentence is written in present tense with the first person in plural nosotros (we), therefore the right conjugation according the list aboveis somos.
Then the complete sentence is:
Nosotros somos mexicanos
We are mexican
The options soy (I am), eres (you are), son (they are) and es (he/she/it/is) are not correct because do not match with the subject in the sentence in number or in genre.
