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.

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.

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，...
