答案不是说increase diversification吗

问题如下：

The most likely effect on a portfolio’s diversification when exposure to direct lending commences is that it:

选项：

A.decreases.

B.remains the same.

C.increases

解释：

While private capital can have overall positive contributions to diversification, direct lending can involve a large capital commitment to a single borrower, with increased concentration risk and reduced diversification. Investors attempt to protect against the risk of direct lending by having the debt itself classified as senior and secured with protective covenants in place to benefit from the associated higher interest rates while reducing non-diversifiable specific risk associated with a single borrower.
