解释：
请问这道题，为什么是 must be the problem of inventory呢？ quick ratio也可以是cash+marketable securities +receivable啊， 而current ratio的增加也可能是current liability的减少啊。

我觉得应该是C啊？ 还是说我没读明白B、C的意思，明显排除了存货之后，标明应收现在状况不好啊
没转过来，我选的C这两个比率都是越高越好，current 受了存货的影响更高，quick没有存货影响后更低，所以不是应该存货的状态比较好，问题存在receivable 上吗
quiratioo分子可以写成CA-InV或者cash + mktable security + receivable对吧？所以inventory或者receivables以及mktable security有什么不对吗
