will expire in-the-money 是什么意思？

问题如下：

How does a decrease in the strike price of a call option affect its likelihood of expiring in-the-money?

选项：

A.Lower B.Unchanged C.Higher

解释：

A lower strike price increases the probability that a call option will expire in-the-money as it's more likely to be above the market price of the underlying asset. 降低行权价格会增加看涨期权到期时处于实值状态的概率，因为它更可能高于标的资产的市场价格。
