A. needn have got stuck
B. couldn have got stuck
C. must have got stuck
D. should have got stuck
答案：
A. needn have got stuck
B. couldn have got stuck
C. must have got stuck
D. should have got stuck
解析：CC 考察情态动词。Needn’t have done sth本不必做某事，couldn’t have done sth不可能做某事；must have done一定做了某事；should have done本应该做某事；题干考察的是情态动词的用法，表示对过去情况的推测。根据到饭店花了很长时间才知道，一定是遇见了交通堵塞。是对过去情况的一种肯定推测。故C正确。
