you have finished this book  是现在完成时态,它表示其动作或状态从过去的某个时间开始,一直持续到某个时间,或者对现在造成某种结果或影响.明显这个句子是强调对现在造成的某种结果和影响.
这个句子其实是一个假设,也就是状语从句, 前面是强调对现在的影响,所以后面用将来时,因为现在还没有感冒! B 选项是现在完成,那这个时态放句子里表示什么意思呢?由现在完成本身的含义可知是错误的.A 表明的是现在的状态,但是这个是一种假设,现在还没有感冒!所以,答案选C

应该是 had got吧,现在完成时是现在时,但它表示过去的动作呀,过去之前(过去的过去)应该用完成时吧。

这两个动作是有先后顺序的,所以时态也是有先后的。
