Question

El auto es _________ hermanas.
a.
a las
c.
a los
b.
de las
d.
de los

Answer 1

Hermanas is feminine and plural, so the answer would be de las. The literal translation is "The car of the sisters." That's how you show ownership in Spanish. You can't say "The sister's car" in Spanish like you can in English, because it'd be incorrect.
