<h2>Right answer: nos</h2>
This is a good example of the usage of the Direct Object, which is the part of the sentence that <u>directly</u> receives the action of the verb. It is used to replace a person, animal or thing in the conversation or in the writing in order to avoid repetition; when they have already been seen in a sentence or external context where the statement occurs.
In this case who directly recieves the action of the verb pregunta (to ask) is nosotros (us), hence nosotros is the<u> direct object</u>.
Now, in order to substitute this direct object we can use the Direct Object Pronouns, which are written before the verb, when it is conjugated.
Here the pronoun nosotros is the <u>1st person plural</u> and <u>its direct object pronoun</u> is <u>nos</u>.
Therefore, the complete sentence is:
<h2>Sofía nos pregunta (a nosotros)</h2>
Sofia asks (us)
