What direct object has been replaced by the direct object pronoun in the
sentence above?
O Nosotros
Ellas
Las herramientas
El volante

Respuesta :

“Las herramientas”

Because it means the tools and that’s something a mechanic would love

Answer: las herramientas

Sentence: El mecánico usa las herramientas y nos dice que son sus favoritas.

Translation: The mechanic uses the tools and tells us that they are his favorites.

Explanation:

Since the direct object pronoun is "las", which is feminine and plural and must agree with the direct object in gender and number, the direct object must also be a feminine and polural noun. The only feminine and plural noun option is "las herramientas".
