Im not 100% but i think The answer is B. :) Hope this helps rmember im not 100% so correct me if im wrong.
I think D is the best answer choice. for a work written around the time of the salem witch trials, you can better understand why extreme fear and condemnation of witchcraft might show up, and the author's purpose is a major thing to understand a work. C doesn't really make sense, because historical context is based on facts, so the context doesn't so much help you understand an author's attitude/opinion. B is true to some degree, but D is still a stronger answer as B is somewhat circular; historical context is an inherent part of a historical character? and A doesn't even make sense to me but i personally would go with D
The main idea is to let both sides of the argument make up and live to the law or god(im not too sure)
