嗨，从没放弃的小努力你好：
同学你好，本题考查的是CML曲线的理解，对于这个曲线我们通常表述为The portfolio under the CML is considered inferior;The portfolio above the CML is considered unachievable.高于CML曲线的点，由于其无差异曲线和其CML曲线不相切（交）是根本无法完成的。这个算是咱们习惯的表述。

The portfolio above the CML is consireinefficient. The portfolio above the CML is consireunachievable. C is correct. Any portfolio thplots above the CML is unachievable, anany portfolio thplots below the CML is inferior to any point on the CML.他是和有效前沿的连接点，那不是在上面的话，不在有效前沿上、应该是无效的啊，为什么2，无效不对？
