问题如下：
In a country where dividend and capital gains are taxed at lower rates than interest income, and realized capital losses can be used to offset realized capital gains. A taxable investor could obtain highest tax-efficient if his taxable account hold more:
选项：
A.investment grade bonds
B.stocks focused on dividend distribution
C.stocks focused on capital gain opportunities.
解释：
C is correct.
考点：asset allocation中的税收限制
解析：应税账户中应当首先考虑征税低、或者可以抵减税收的资产。题中，dividend与capital gain的税率比interest income低，首先排除A。由于realized capital losses可以抵减realized capital gains（这被称为tax-loss harvesting），关注于capital gain的股票一旦获得损失可以抵减当前或者未来的capital gain，所以C更好。
根据题目意思，B拿分红，税比bond 的interest income更低；如果产生了CG loss还可以抵扣，不是很好吗？
C的意思感觉很矛盾，如果盈利了则会有更高的CG tax，但总不能一开始冲着会产生CG loss去选股吧
