Answer:
C) Coupon bonds always trade for a discount.
Step-by-step explanation:
"A coupon bond, also referred to as a bearer bond or bond coupon, is a debt obligation with coupons attached that represent semiannual interest payments. With coupon bonds, there are no records of the purchaser kept by the issuer; the purchaser's name is also not printed on any kind of certificate. Bondholders receive these coupons during the period between the issuance of the bond and the maturity of the bond." Trade them for a discount is not a common characteristic of coupon bonds.
