Answer:
The right possessive adjective in the conversation is:
- <u><em>Nuestros</em></u>.
<em>- </em><em>Buenos días, señora Méndez. ¿Es Tina su sobrina? </em>
<em>- </em><em>Sí, mi esposo y yo tenemos dos sobrinos, Tina y Pedro son </em><em><u>nuestros</u></em><em> </em><em>sobrinos.</em>
Explanation:
The translation of the conversation is:
- Good morning, Mrs. Méndez. Is Tina your niece?
- Yes, my husband and I have two nephews, Tina and Pedro are <u>our</u> nephews.
The possessive adjectives are used to mention the direct or indirect ownership from something or somebody, <u>these must be linked to the noun who realizes the action</u>. The adjectives taking into account the personal pronoun are:
- <em>Yo: </em><em>mi</em><em>.
</em>
- <em>Tú: </em><em>tu</em><em>.
</em>
- <em>Él: </em><em>su</em><em>.
</em>
- <em>Ella: </em><em>su</em><em>.
</em>
- <em>Ello: </em><em>su</em><em>.
</em>
- <em>Nosotros: </em><em><u>nuestro(s)</u></em><em>, </em><em>nuestra(s)</em><em>.
</em>
- <em>Ellos: </em><em>su</em><em>.
</em>
As the holders in the conversation are Mrs. Méndez and her husband, the personal pronoun that must be revised is <em>"nosotros,"</em> and since <em>"los sobrinos"</em> are a male and plural noun, the form used must end in <em>"os,"</em> therefore the correct adjective is <u><em>"nuestros."</em></u>
