C.Commercianinterbank interest rates move inversely to officiinterest rates. is correct.Centrbank activities are typically intento maintain pristability. Concerning choinote ththe transmission channels of monetary poliare not inpennt.考点 Monetary policy解析A央行的首要宗旨就是稳定物价，所以A正确。B错在四条渠道并非孤立的关系而是相互联系的关系。C错在银行间利借贷利率与市场利率之间的关系应该是正相关、而非负相关。 关于B，公开市场操作不算吗？

老师问下 货币政策不是总共三种工具吗 再贷款利率 银行准备金 和公开市场操作 为啥是四种

    请问B，four inpennt channels具体是哪四种呢？另外可以一下为什么不是Inpennt的吗？谢谢！
