问题如下：
Which of the following conditions is least likely to be an ideal currency regime?
选项：
A.All currencies are fully convertible.
B.The monetary policy which is fully independent.
C.Independently floating exchange rates.
解释：
C is correct.
The ideal currency regime would have three properties. First, the exchange rate between any two currencies would be credibly fixed. Second, all currencies would be convertible as far as possible.Third, each country's monetary policy is independent , so they can achieve domestic objectives.
考点：Exchange Rate Regimes
解析：
理想的货币制度有三个特点。首先，任何两种货币之间的汇率都将可靠地固定下来。其次，所有货币都将尽可能实现自由兑换。第三，每个国家的货币政策都是独立的，因此它们可以实现国内目标。
这三点是不可能同时实现的，具体原因会在二级进行详细学习，这里，大家掌握记住这个结论即可。
请问这道题在notes哪里？为什么不选A？
