问题如下：
The price of a forward contract on an asset with no benefits and costs would be :
选项：
A. the expected spot price at expiration.
B. the spot price compounded at the risk-free rate over the life of the contract.
C. the spot price compounded at the risk-free rate plus risk premium over the life of the contract.
解释：
B is correct. The forward price is based on arbitrage, which is the spot price compounded at the risk-free rate over the life of the contract.
中文解析：
FP=S0*（1+rf）T 这个公式和B选项的文字描述一样。
B选项说the spot price compounded at risk free rate 也就是S0在合约期间以无风险利率复利，结果就是S0*（1+rf）T 。
A為什麼不對，Forward price不是定死的嘛
