I personally would say c) irony.
Why?
Alliteration is like the sally seashells kids song.
Metaphor is saying " he is a rock" when "he" is not actually a rock
Hyperbole is something exaggerated or a claim.
That makes me believe it is irony. Hope this helps.
Answer:
This poem uses the techniques of simile ("as the deer") and sensory imagery ("eyes watchful").
Explanation:
The poem is a simile poem, meaning the entire poem is a simile. Line 2 contains the comparison “and we are like the deer” and the rest of the poem describes in what manner his people are like the deer.
