To find the correct direct object pronoun, identify the object. Our object is unas sillas, which is feminine plural.

The options

A. los - the ~masc. plural

B. la - the ~fem. singular

C. las - the ~fem. plural

D. lo - the ~masc. singular

The gender and grammatical number between the object and the object pronoun must agree, thus the correct answer is (C).

C. las
