B为什么不对

问题如下：

Raye believes the previous adviser’s specification for debt is incorrect given that, for purposes of asset allocation, asset classes should be:

选项：

A.

diversifying.

B.

mutually exclusive.

C.

relatively homogeneous.

解释：

C is correct. In order to effectively specify asset classes for the purpose of asset allocation, assets within an asset class should be relatively homogeneous and have similar attributes. The previous adviser’s specification of the debt asset class includes global investment-grade corporate bonds and real estate. This definition results in a nonhomogeneous asset class.
