问题如下：
Which of the following statements about derivatives is correct?
选项：
A. High own capital is required at initiation of a derivative contract.
B. Adding derivatives to a portfolio will increase risk.
C. The value of a derivative is relative to the underlying asset and interest rate.
解释：
C is correct. Derivatives can be used to manage risk. In addition, derivatives have a high degree of leverage, traders need to invest a small amount of capital at initiation.
Adding derivatives to a portfolio will increase risk. 这句话我认为没有问题，衍生品会使得组合可能的收益率和风险都大幅提高。 难道这句话是错在了will了吗？
