This is part of an answer someone had to this same question.
the correct answer would be the letter choice A
The main reason the league opposed the war is because they believed that the war was immoral and undemocratic.
They enforce the laws of the land, and keep everything and everyone in line.
The correct answer is "Parents refused to care for their dying children".
The situation to which the narrator is referring to as "even worse, and almost incredible" during the plage, is that parents were abandoning their suffering children. <u>This is what he found to be the most poignant and striking image that conveyed the extent of the horrors brought by the plague</u>. Mothers and fathers refused to care for their dying children or even visit them in innumerable cases.
Hope this helps!
