B. shouldn’t have spoken

C. needn’t have spoken

D. couldn’t have spoken

答案：

A. mustn’t have spoken

B. shouldn’t have spoken

C. needn’t have spoken

(答案→)D. couldn’t have spoken

解析：句意：今天早晨我没有在会议室看见她，她不可能在会上发言。mustn’t have spoken没有这个用法；shouldn’t have spoken表示不应该发言而发言了；needn’t have spoken没必要发言而发言了；couldn’t have spoken不可能发言。根据句意故选D。
