问题如下：
The most appropriate response to Payne’s tax-related question is:
选项：
A.on all income earned worldwide. B.only on income earned where Payne is a citizen. C.only on income earned where Payne is a resident.解释：
A is correct. If Payne becomes a resident of Singapore but maintains her US citizenship, any income she receives worldwide will be subject to US tax, because the United States is one of the few countries that taxes citizens on a worldwide basis, regardless of residence.
我不太懂B是什么意思。如果他是美国的公民，那他就是全球征税，为什么不能选B呢？B的意思不是说的就是他是美国公民吗？
