远期承诺的回报为什么是线性的？

问题如下：

Which type of derivative is characterized by a payoff that is non-liner?

选项：

A.Only contingent claims B.Only forward commitments C.Both contingent claims and forward commitments

解释：

Non-linear payoffs are typical of contingent claims where the payoff depends on a certain event occurring, unlike forward commitments that have linear payoffs. 非线性回报通常出现在条件性索赔中，其回报取决于某个特定事件的发生，不同于具有线性回报的远期承诺。
