▲你的句子确实应选 B。to make matters worse 是习语（许多词典都用黑体字列出，作为习语处理），意思是“使情况更糟的是”（主要用作插入语），英语词典对此的解释是：used to say that something makes a bad situation worse

▲例句：

To make matters worse, he refused to apologize. 更糟的是他拒不道歉。

To make matters worse, it started to rain again. 更糟的是，又开始下雨了。

To make matters worse, my friend then lost her keys. 更为糟糕的是，我的朋友又弄丢了她的钥匙。

Three of our players were ill, and to make matters worse, our main scorer had broken his ankle. 我们的3名队员病了，更糟的是，主要得分手摔断了脚踝。

▲除用作插入语外，也可用于谓语部分。如：

Don't say anything—you'll only make matters worse. 什么也别说——你只会把事情弄得更糟。

Don’t let yourself despair; this will only make matters worse. 不要想不开，这样只能使情况变得更糟。

Let him say what he will, he cannot make matters worse. 不管他说什么，他也不会使事态变得更糟了。

If you're an ostrich about your debts, you're only going to make matters worse: it would be much better to take your head out of the sand and face facts, however unpleasant. 如果你不愿正视自己的债务问题，只会让事情变得更糟糕。

▲其实用现在分词形式的 making matters worse 也不是不可能，比如当用作结果状语时，就可能这样用。例如：

This of course, simply depresses world prices further, making matters worse for them. 当然这只会使全球价格更不景气，对他们来说情况也就变得更糟。
