Explanation : The coupon payments on a floating-rate bond that is tied to the six-month
Libor will reset every six months, based on changes in Libor. Thus, as
Libor increases, so will the coupon payments. A is incorrect because the
spread on a floating-rate bond is typically constant; it is set when the
bond is issued and does not change afterward. C is incorrect because the
issuer’s credit quality affects the spread and thus the coupon rate that
serves as the basis for the calculation of the coupon payments, but only
when the spread is see that is, at issuance.
