Answer: A) Allusion.
Step-by-step explanation: An allusion is a literary device that consists in making a brief reference to a person, an event (historical, political, cultural, or any other important event), or a place. If Fernando is reading a passage in which he sees a reference to a well-known person, event, place, literary work or work of art, he has come across with an allusion. So the correct answer is the corresponding to option A.
