She may have missed the train, in ________ case she won't arrive for another hour．

She may have missed the train, in ________ case she won't arrive for another hour．

答案C
此题容易误选 A，因为不少同学认为在定语从句中能用做定语的关系代词的只有 whose。其实除 whose可用做定语外，which也可用做定语，只是含义上有差别：在此情况下，whose的意思相当于one's，而 which的意思则相当于 that或 this。
