Question

7 multiple choice 2 points ¿es elena \their cousin\? vuestra prima vuestras prima sus prima su prima

Explanation:

To solve this, we analyze the possessive adjectives and noun agreement in Spanish. The question is about "their cousin" (feminine, singular "prima").

• "vuestra" is "your (familiar plural, feminine)", not "their" so first option is out.
• "vuestras" is plural feminine possessive, but "prima" is singular, so second option is incorrect (noun - adjective agreement fails).
• "sus" is plural possessive (for "their"), but "prima" is singular. In Spanish, for singular noun with "their" (when the owned noun is singular), we use "su" (since "sus" is for plural nouns owned). Wait, no: "su" can mean "his/her/its/their" (singular or plural possessor, depending on the noun). Wait, the noun here is "prima" (singular feminine). So "su prima" would mean "his/her/their cousin" (if the cousin is singular). Let's check:
• "sus prima" is wrong because "sus" is plural possessive adjective, and "prima" is singular (adjective and noun must agree in number). So "sus" (plural) with "prima" (singular) is incorrect.
• "su prima": "su" is a possessive adjective that can mean "their" (when the possessor is plural and the possessed noun is singular). For example, "Ellos tienen su prima" (They have their cousin) – here "prima" is singular, so "su" (not "sus") is used because the noun is singular. The other options: "vuestra" is "your (plural familiar, feminine)", not "their". "vuestras" is plural, "prima" is singular – mismatch. "sus" is plural, "prima" is singular – mismatch. So the correct one is "su prima".

Answer:

D. su prima
