单选题 Given the covered call option diagram below and the following information, what are the dollar values for points X and Y? The market price of the stock is $70, the strike price of the call is $80, and the call premium is $5.

A、 $75, and point Y represents a dollar value of $15.
B、 $70, and point Y represents a dollar value of $15.
C、 $80, and point Y represents a dollar value of $15.

【正确答案】 C

【答案解析】The kink in the diagram of a covered call is always at the exercise price of the option. Therefore, point X is $80. As the stock price rises above $80, the stock is called away and the maximum gain is the call premium plus the stock price gain ( $80 - $70 ). The maximum gain, then, at point Y is ( $5 + $10 = $15).
