C是什么？

问题如下：

The investment process followed by DFC’s previous fixed-income manager is best described as:

选项：

asset-driven liabilities.

liability-driven investing.

asset–liability management.

解释：

C is correct.

Asset–liability management strategies consider both assets and liabilities in the portfolio decision-making process. Mowery notes that DFC’s previous fixed-income manager attempted to control for interest rate risk by focusing on both the asset and the liability side of the company’s balance sheet. The previous manager thus followed an asset–liability management strategy.

我们分类里不是只有A和B吗？然后我看到，这个公司是ASSet 管理公司，那主营业务不是Asset吗？那不是应该是A吗
