B. 
C. 
解释：
你好，我就想确认一下我的理解对不对，因为英文不是很熟悉，B选项中的amortization of the premium指的是每一年除了归还的利息，还归还部分本金，那么，这些每年部分归还的本金就是这个英文意思，是么？谢啦。还有A选项的Carry account是什么意思

B的amotization of the premium 和amortization cost 搞错了，哎amortization cost是下降的，因为是bonpayable但是amortization of premium指的就是摊销的本身

amortization of the premium increases eayear. premium is evenly amortizeover the life of the bon B is correct. The amortization of the premium equals the interest payment minus the interest expense. The interest payment is constant anthe interest expense creases the carrying amount creases. a result, the amortization of the premium increases eayear.随着时间的推移，interest和coupon的差异越来越小，amortization of premium为什么会越来越大呢？
