It’s ellos...A !!!!!!!!!!!!!!!
Answer:
las montañas estan detras del rio (A)
<h2>Correct answer:</h2><h3>C. Si, les gustan las fiestas.</h3>
Les is the indirect object pronoun for the third person plural. An Indirect Object Pronoun is a person that receives the action of a verb indirectly. Its purpose is to tell you <em>to whom</em> or<em> for whom</em> something is done. So the action in this sentence is being performed <em>for my friends (for them). </em>Since mis amigos is a plural noun, we choose gustan as the conjugation of the verb gustar. Finally:
<em>¿A tus amigos les gustan las fiestas?</em>
<em>Sí, les gustan las fiestas</em>
