Nuestra profesora es muy simpática. tiene mucha paciencia con nosotros y da mucho tiempo libre. a. me b. te c. nos d. les

The answer is C. Nos. That is because it refers to us.

Nuestra profesora es muy simpática. Tiene mucha paciencia con nosotros y nos da mucho tiempo libre.

Translation:

Our teacher is very nice. She has a lot of patience with us and gives us lots of free time.

Explanation:

In the sentence given, the subject is nuestra profesora (our teacher). Nosotros (us) is the direct object.

(She gives us lots of free time.)

The direct object denotes the person or thing that receives the action of a transitive verb, which often uses the proposition "a" when the verb is referring to a person or an animal.

Now, the sentence and the exercise is meant to showcase the direct object pronoun. Direct object pronouns are used to replace the direct object.

In this sentence, nosotros is the direct object, while nos is the direct object pronoun. If the pronoun hadn't been used, the sentence would have read: "Tiene mucha paciencia con nosotros y nos da mucho tiempo libre a nosotros.", which would have been redundant.
