问题如下图：
选项：
A. 
B. 
C. 
解释：
这题也不懂，三个选项都是CAMP的假设，为什么只选B。也看了其他解析，老师说因为market portfolio只要求有相同预期，而market portfolio不是CML里的概念吗？所以本题其实是在考CML而不是CAMP对不对？
感谢解答。
NO.PZ2015121801000111 问题如下 With respeto capitmarket theory, whiof the following assumptions allows for the existenof the market portfolio? All investors: A.are pritakers. B.have homogeneous expectations. C.plfor the same, single holng perio is correct.The homogeneous expectations assumption means thall investors analyze securities in the same wanare rational. This, they use the same probability stributions, use the same inputs for future cash flows, anarrive the same valuations. Because their valuation of all assets is intical, they will generate the same optimrisky portfolio, whiis the market portfolio. 框架图里assumption这三个都有，都是原话。怎么就非得选相同预期呢，得太牵强了
