I don’t know, I’m a freshman, sorry m8
The correct answer is "D: Raúl, Rafael and Federico".
Pablo Neruda describes various details of his everyday life when he was living in Spain (He is Chilean). In lines 18-23, he mentions:
- "Federico, do you remember?"
After these 3 lines, he says: "Brother, my brother!" in order to refer to the later 3 as his brothers.
I would go with B because he sounded very bold and proud but at the same time he sounded concerned about what is going to happen.
