他不可能给我写信了.can't have done 不可能,表示对过去的猜测.
or I'd have got the letter by now.= or I would have got the letter by now
否则的话,我现在已经收到信了.
否则的话,也就是 如果她给我写了信的话.
这里是与过去 事实相反的虚拟条件句,If sb.had done...,sb.would have done...
所以C答案正确.

我觉得这个‘d 也可能指的是should，这里表示虚拟语气， 她一定没有写信给我，要不然我现在应该已经收到信了

这个有时视情况而定。'd 有时等于 had ，有时是would,或者是should。
这个句子意思应该为：她不可能给我写过信，要不然，现在我早收到了。
至于这个题中'd 很显然指的是 would或者是should，因为后边跟的是动词原形。had做助动词讲时，一般是过去完成时的标志之一，后边跟过去分词。
但是，“would+have+done”虚拟语气，表示对过去事情的假设，...

这个有时视情况而定。'd 有时等于 had ，有时是would,或者是should。
这个句子意思应该为：她不可能给我写过信，要不然，现在我早收到了。
至于这个题中'd 很显然指的是 would或者是should，因为后边跟的是动词原形。had做助动词讲时，一般是过去完成时的标志之一，后边跟过去分词。
但是，“would+have+done”虚拟语气，表示对过去事情的假设，意思是“本来会怎样却没有怎样”。
例子： I would have told you all about the boy's story, but you didn't ask me. 我本来会告诉你这个小男孩的故事，但是你没有问我。
“should+have+done”意思是“本来应该做某事，而实际没做。” “shouldn't+have+done”表示本来不应该做某事，而实际做了。含有指责对方或自责的含意。
根据句意推敲，应该是：would have done ，本来应该发生的事情，却没有发生。
希望我的回答对你有所帮助！
