请问这道题怎么理解，解释一下

问题如下：

If a bank manager is concerned about a high cost of liquidity risk, she is most likely concerned about:

选项：

A.

selling assets quickly at fair market prices.

B.

receiving lower than expected cash inflows in the future.

C.

generating positive cash flows from its sources of liquidity.

D.

a high interest rate for borrowing relative to the risk-free rate.

解释：

融资成本风险（流动性风险的成本）是指当银行需要获取流动性来源时，其支付的利率与无风险利率之间存在较大利差的风险。快速以公平市场价格出售资产的能力属于市场流动性风险。未来收到低于预期的现金流入是总体定量流动性风险。从流动性来源产生正向现金流则是流动性生成能力。
