How would you rewrite the following sentence using object pronoun(s)? amo a mis hermanas. los amo. amo las. las amo. la amo.

Hello!

The correct way to rewrite the following sentence using object pronoun(s) is Las amo

The pronoun, in this case, is Las. Las is firstly a pronoun used for feminine subjects. In this case, the subject is "hermanas" ("sisters" in English). As "sisters" is feminine, the pronoun should be feminine too. 

Next, Las is a pronoun used for plural subjects. "Sisters" is a plural subject, so a plural pronoun should be used. 

Of the listed pronouns, the only one that is feminine and plural is "Las", meaning that this is the correct object pronoun.

Have a nice day!
