Answer:
The 10 year callable bond will appreciate more than the 5 year callable bond.
Step-by-step explanation:
A callable bond is a type of bond which the issuer may call back, may purchase it back from the holder at a date before the stated maturity date to pay off debt early. In this case, if the interest rates fall by 200 basis points, the five year callable bond can be called in 5 years time if the issuer believes it to be more beneficial and so will appreciate less than the 10 year callable bond.
