Select one:

a.The yield on the 5-year T-bond must be smaller than the yield on the 5-year AAA corporate bond.

b.The yield on the 10-year AAA corporate bond must be larger than the yield on the 5-year T-bond.

c.The yield on the 5-year T-bond must be smaller than the yield on the 10-year B corporate bond.

d.The yield on the 5-year AAA corporate bond must be larger than the yield on 5-year B corporate bond.

e.The yield on the 10-year T-bond must be larger than the yield on a 2-year T-bond.
