A bond portfolio manager is considering three Bonds – A, B, and C – for his portfolio. Bond A allows the issuer to call the bond before stated maturity, Bond B allows the investor to put the bond back to the issuer before stated maturity, and Bond C contains no embedded options. The bonds are otherwise identical. The manager tells his assistant, “Bond A and Bond B should have larger nominal yield spreads to a U.S. Treasury than Bond C to compensate for their embedded options.” Is the manager most likely correct?（）
