______ to my surprise, she failed in the College Entrance Exam. A. Much B. More C. Too much D. Much more

我们先看句子的含义：“______ to my surprise, she failed in the College Entrance Exam.”（令我________的是，她高考没考好。）

这里的固定搭配是 to my surprise（令我惊讶）。
表示“非常惊讶”时，习惯上用 much to my surprise，意思是“令我大为惊讶”。
其他选项 more, too much, much more 不与此固定短语搭配。

所以正确选项是：

A. Much
