B. A floor is an advantage to both the issuer and the bondholder while a cap is a disadvantage to both the issuer and the bondholder.
C. A cap is a disadvantage to the bondholder while a floor is a disadvantage to the issuer.
参考答案：C
解析：
A cap limits the upside potential of the coupon rate paid on the floating rate bond and is therefore a disadvantage to the bondholder. A floor limits the downside potential of the coupon rate and is therefore a disadvantage to the bond issuer.
