选项：
A.GAAP, decision-useful, sustainable, and adequate returns
B.Within GAAP, but "earnings management"
C.GAAP, decision-useful, not sustainable, Low "earnings quality"
解释：
B is correct.
考点：Quality Spectrum Of Financial Reports
解析：这个题考的是一级财务的知识
题干说了公司是遵守会计准则的(GAAP)，注意这里不是指US GAAP，而是说公司遵守了普遍适用的会计准则，但是earning 有问题，所以选B。具体描述：Reporting is compliant with GAAP, but the amount of earnings is actively managed to increase, decrease, or smooth reported earnings.
B 和C 明显的区别点是什么？
什么时候是non sustainable ，“low earning quality” 这里一般说业务或者earning return低？有什么例子
