Answer:
The structure of the poem is Free verse-(B.)
A and D are grammatically correct! B and C are 100% incorrect.
In A, you can write "You are quite a..." as "You're quiet a...", but in D ,i don't see an error. So it's a 50-50 in my opinion.
I'm not a 100% sure on the right answer, but i can assure you that the answer is either A or D. Hope it helps!
I wouldn't completely trust myself here, but I would choose answer C) War. And this is simply because of the language that's used, and the aggression in some of the words.
"...let slip the dogs of war;..." "..Blood and destruction shall be so in use.."
Things of that nature are pretty out there in his soliloquy, which makes me think he's in support of war. But I'm so unsure... I really do apologize :)
B is the correct answer because it's the only one that uses the correct grammar.
