Number 2 is the answer I think
The correct answer is A. Subjective narrator.
When a narrator is subjective, this one expresses or adopts the point of view of a specific character in the story. He usually knows what the character feels or think, but not what the other characters maybe thinking or doing. He has a limited vision of what is occurring in the story.
I'd go with the second choice, it has the most detail and sensory imagery. As it has him singing a sad song while burying the bird.
