Question

You pass a friend on the street in the evening and your friend says "¡hola!" to you. how would you respond? (1 point) por favor. yo soy carlota. ¡buenas noches! ¿cómo te llamas?

Answer 1

Because it indicates that you already know this person you would not ask their name (Como te llamas), nor would you introduce yourself (yo soy carlota), so the only other answer that would make sense would be buenos noches, because it is in the evening.
Hope this helped!
