这道题a错在哪里请问请问请问

问题如下：

If a central bank increases the reserve requirements, which of the following statements is least correct?

选项：

The central bank restricts money creation.

A contractionary monetary policy is used.

The supply of money will increase.

解释：

C is correct.

Raising reserve requirements should limit the supply of money. It also refers to a contractionary monetary policy.

考点： reserve requirements

解析： reserve requirements 是央行要求商业银行需要存放在其那里的现金。

如果 reserve requirements 增加，那就表明商业银行需要把更多的货币放到央行那儿，那么货币制造就会减少，货币供给也相应减少，这是一种紧缩的货币政策，所以C选项入选。
