选项：
A.
in-the-money.
B.
at-the-money.
C.
out-of-the-money.
解释：
A is correct. When the price of the underlying is below the exercise price for a put, the option is said to be in-the-money. If the price of the underlying is the same as the exercise price, the put is at-the-money and if it is above the exercise price, the put is out-of-the-money.
in是好的 at是相等的 out是不好的 put option 是卖权 那价格低于现货价格 不应该是out 不好的吗
