问题如下：
Peter Cavuto lives in a country that imposes a wealth tax of 0.5 percent on financial assets each year. His €500,000 portfolio is expected to return 5 percent per year over the next twenty years. Assuming no other taxes, what is Cavuto’s expected wealth at the end of twenty years?
选项：

B.€1,205,857.
C.€1,326,649.
解释：
