问题 What are they doing? They______a meeting.

选项 A、must have
B、may have
C、might be having
D、could be having

答案C

解析该题是语法结构题，考查的是情态动词的用法。选项A表示命令，不合题意。选项B表示猜测，但是时态不正确，前面的问句用的是现在进行时态，回答也要求用同样的时态。选项D中的情态动词could也可以用来表示猜测，但它是用在否定句和疑问句中表示猜测，如：You can’t／couldn’t be a student．你肯定不是学生。在陈述句中通常用may／might+动词表示猜测。因此，根据题意和语法规则，选项C为最佳答案。
