Answer:
C.
Step-by-step explanation:
It's not a simile beacuse a simile compares things using 'like' or 'as'
It's not a metaphor because it's not comparing two objects.
It's not a onomatopoeia because it's not referring to the sound of them hitting the ground or the bullet.
This doesn't seem like it uses any figurative language so I'm just going to say personification.
