Choose the word that best completes the following sentence. Gregorio la puerta del cuarto.

The sentence means “Gregorio ___ the room door.” The verb “abre” means “opens,” so “Gregorio abre la puerta del cuarto” is the natural and grammatically correct sentence. “Copia” means copies, “guarda” means puts away or keeps, and “reinicia” means restarts; none fits the door in this context.
