Company XYZ is a U.

XYZ bonds have a yield higher than the coupon rate, indicating that their market price has decreased due to concerns about the issuer's creditworthiness.

A is correct because the high yield suggests elevated credit risk.

B is incorrect because domestic utility companies are unlikely to face political risk.

C is irrelevant as the bonds are denominated in U.S. dollars.

D is incorrect as prepayment risk is associated with callable bonds, not noncallable bonds.
