问题如下：
Marie Co. plans to issue a long-term debt in next few days. The management notice that central bank releases a signal of tight monetary policy and the interest rate is expected to increase. Which type of bond will benefit the Marie Co. most?
选项：
A. A step-up coupon bond.
B. An inflation-linked bond.
C. A floating-rate bond with cap rate.
解释：
C is correct.
The cap of floating rate bond can limit the upper level of coupon payment. Therefore it can protect the issuer from increasing interest rate. Both step-up and inflation-linked bond will be preferred by bondholders not the issuer under the increasing interest rate condition.
floating rate notes和 inflation linked bond如果不加cap的条件，对issuer的保护是不是一样的？
