Answer:
Alliteration, Onomatopoeia, and Allusion.
Explanation:
In Act 2 Scene 1, Macbeth states "It is the bloody business which informs" in his monologue about his hallucination of a dagger. The words "bloody" and "business" start with the same letter, adding emphasis to the phrase. This is alliteration.
In Act 2 Scene 2, Macbeth shouts "Who’s there? What, h(o)!" He exclaims "h(o)" out of fear and surprise, which is an example of onomatopoeia.
In Act 2 Scene 2, Macbeth says "Will all great Neptune’s ocean wash this blood / Clean from my hand?" This statement alludes to Neptune's Ocean, an immense and powerful body of water.
