问题补充：

We at the airport; otherwise we would have arrived home by lunch time.

A. had delayed

B. were delayed

C. had been delayed

D. have delayed

答案：

A. had delayed

(答案→)B. were delayed

C. had been delayed

D. have delayed

解析：句意：我们在机场被耽搁了，否则我们到午餐的时候，就可以到家了。根据we would have arrived home by lunch time.可知这是对过去的事情的虚拟，前面的句子是过去的事实，而且we和delay是被动关系，所以选B。
