Hmmm...seems like some of your question is missing?
Since you're asking for the most effective sensory detail, it would be D.
Answer:
The character that says these words is Satan. He is speaking to the other fallen angels.
Explanation:
Before these lines begin, it is said that Satan is going to say the following words "whereto with speedy words th' Arch-fiend repli'd." The "arch-fiend" is like a super enemy, arch (means superior) fiend (enemy).
Two of the main phrases that prove that Satan is talking are the following:
- "<em>To do aught good never will be our task, But ever to do ill our sole delight" </em>= Doing good action will never be our thing, we only find pleasure in doing bad things.
- <em>"As being the contrary to his high will whom we resist"</em> = since we are the contrary of God, the one we resist.
Trust maybe? i’m not sure but that’s what it seems like
