<h2>Right answer:</h2><h3>Recoger el auricular</h3>
<h2>Explanation:</h2>
to pick up means recoger. On the other hand, el auricular translates into the headphones, which is a piece of equipment that you wear over your ears in order to listen to the radio or recorded sound. So you are performing an action, that is, you are picking the auricular up. Perhaps these headphones are on the floor and you look at this.
The last one your welcome lol
