单选题 Most of the civil servants involved in the affair have been successfully ______ and sentenced.

A、 prosecuted
B、 propagated

【正确答案】 A

【答案解析】[解析] 上下文语义。根据句中civil servants，sentenced(判决；审判)提供的语境，说明空格应填入与法律相关的词。选项中，只有prosecute(起诉，告发)符合要求。故答案为A。propagate“传播，传送；繁殖”；persecute“迫害，困扰”；precipitate“使沉淀；促成”。
