I told your friend how to get to the hotel, but perhaps Ihave driven her here.

A. could

B. should

C. must

D. might

答案：

A. could

(答案→)B. should

C. must

D. might

解析：考查情态动词用法。Could have done sth本可以做某事；should have done本应该做某事，实际上却没有做；must have done一定做了某事。Might have done也许做某事。句意：我告诉你的朋友如何到宾馆的，但是也许我本应该开车送她去那里。根据句意说明B正确。
