问题如下：
At expiration, a European put option will be valuable if the exercise price is:
选项：
A.
less than the underlying price.
B.
equal to the underlying price.
C.
greater than the underlying price.
解释：
C is correct. A European put option will be valuable at expiration if the exercise price is greater than the underlying price. The holder can put (deliver) the underlying and receive the exercise price which is higher than the spot price. A European put option would be worthless if the exercise price was equal to or less than the underlying price.
请问这个题干怎么理解，a European call option，角度是指我买了这个option吗？就是说，做题时，角度应该是期权的买方还是卖方？ 从这一题来看，是指买方？
