问题如下：
The capital market line (CML) is the graph of the risk and return of portfolio combinations consisting of the risk-free asset and:
选项：
A.any risky portfolio.
B.the market portfolio.
C.the leveraged portfolio.
解释：
B is correct.
Although the capital allocation line includes all possible combinations of the risk-free asset and any risky portfolio, the capital market line is a special case of the capital allocation line, which uses the market portfolio as the optimal risky portfolio.
CML是一条经过两点的直线，而CAL有多条，可以和所有风险资产连线，只是切点这条是最好的，这条也是CML。对吧？所以CML不能与所有风险资产、只能与切点。
