(答案→)A. couldn't have attendedB. needn't have attendedC. mustn't have attendedD. shouldn't have attended解析：“情态动词＋完成式”有各自的含义。must have done表示对过去事情的肯定推测，多用于肯定句中；needn't have done表示过去本不必做的事情；shouldn't have done表示过去做了不该做的事情；can't(couldn't)have done表示对过去的否定性推测，意为“不可能”。所提供的情境My sister met him at the Grand表示他不可能参加讲座。
