options:

it shows that abigail can easily fake satanic possession.

it shows that john proctor has been tortured.

It shows that Reverend Hale feels guilty for his role in the trials.

Explanation:

This line is spoken by Reverend Hale in Act IV of "The Crucible" (1953) by Arthur Miller.

Mr. Hale says this line to Danforth that there is blood on his head. It means he (Mr. Hale) feels guilty for his role in the trial. He feels himself responsible for the death of so many innocent people  before Act IV and for those who are to be hanged after that. Although Mr. Hale had got a feeling in about Act II that the accused were innocent, but he could not stand for them, and when he did, it was too late. For this reason Reverend Hale considers himself responsible for the death of innocent people and feels blood on his head.

"Can you not see the blood on my head" just emphasizes the first sentence of the line.

Since this line is spoken by Reverend Hale, so no answer option concerning Parris, Abigail, and John Proctor can be correct

the answer is irony!

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.
