As a bond's time to maturity increases, the bond's sensitivity to interest rate risk:

A. increases at an increasing rate. B. increases at a decreasing rate. C. increases at a constant rate. D. decreases at an increasing rate. E. decreases at a decreasing rate.

Is the answer increasing at a decreasing rate, because increasing time leads to more sensitivity to bond changes in interest rate, and at a decreasing rate because as the bond matures the risk is minimize.
