问题如下：
All else being equal, as the correlation between two assets approaches +1.0, the diversification benefits:
选项：
A.decrease.
B.stay the same.
C.increase.
解释：
A is correct.
As the correlation between two assets approaches +1, diversification benefits decrease. In other words, an increasingly positive correlation indicates an increasingly strong positive linear relationship and fewer diversification benefits.
请教diversification benefits的直译及相关理解
