If an investor has a fixed investment horizon, what type of security can be used to minimize both the price risk and the reinvestment risk?

A zero coupon treasury bond

Explanation:

A zero coupon treasury bond having a maturity period matching the investment horizon of an investor can minimize both price risk and reinvestment risk.  Reinvestment risk in case of a bond refers to reinvestment of the cash flows from the bond at a return close to current investment rate of return. As a zero coupon treasury bond do not pay any coupon payment, it won't carry any reinvestment risk.  

The bond holder in case of a zero coupon treasury bond, receives a guaranteed payment at maturity of the bond. This payment is equal to face value or par value of the bond. Price risk (increase or decrease in a bond value due to interest rates) matters if a bond is sold before maturity.. However, on selling a bond at its maturity, price risk won't matter as the payment will be equal to face or par value.
