问题如下：
An investor may prefer a single hedge fund to a fund of funds if he seeks:
选项：
A.due diligence expertise.
B.better redemption terms.
C.a less complex fee structure.
解释：
C is correct.
Hedge funds of funds have multi-layered fee structures, while the fee structure for a single hedge fund is less complex. Funds of funds presumably have some expertise in conducting due diligence on hedge funds and maybe able to negotiate more favorable redemption terms than could an individual investor in a single hedge fund.
相比于single fund，FOF的最大缺点就是多重费用结构，所以投资者选择single fund的主要原因就是更简单的费用结构，所以C正确；而A选项的更好的尽调经验和C选项更优的赎回条件都是FOF相比与单层基金的优势，不符合题目描述，所以答案是B选项。
答案解析是不是写错了？答案解析写的是选B
