Your answer would be B, <em>however, </em>as conjunctions have different uses. One of the uses of <em>however</em> is when it is followed by an adjective or an adverb. These constructions are used to emphasize that the degree or extent of something cannot change a situation. Therefore, the sentence would be as follows:
(8) However juxtaposed against all the suffering and hatred amongst the peole and within society in the final, and ultimate, sacrificial act of Sidney Carton.
