单选题 Any negative statements and accusations made should be ______ and forthrightly answered, preferably at the level on which they originate.
A. promptly B. thoroughly C. punctually D. exactly

【正确答案】 A

【答案解析】[解析] 根据后面的“preferably at the level on which they originate(最好能在刚产生的时候)”可知，空白处所填词语应表示“迅速地”。在选项中，promptly意为“迅速地，敏捷地”； thoroughly意为“十分地，彻底地”；punctually意为“按时地，如期地”；exactly意为“正确地，严密地”。因此正确答案是A。其他选项与题意不符。
