The lta of a European-style put option moves towarzero the priof the unrlying storises. The gamma of at-the-money European-style option ten to increase the remaining maturity of the option creases. Compareto at-the-money European-style call option, out-of-the- money European-style option with the same strike prianremaining maturity ha greater negative value for theta. ANSWER: D Vega is highest for ATM Europeoptions, so statement A is correct. lta is negative and moves to zero S increases, so statement B is correct. Gamma increases the maturity of ATM option creases, so statement C is correct. Theta is greater (in absolute value) for short-term ATM options, so statement is incorrect. C，随着到期日临近，the money 的gamma上升；in/out the money 的gamma下降。请分别一下为什么？

Theta is greater (in absolute value) for short-term ATM options, so statement is incorrect. 关于答案错误的原因Theta is greater (in absolute value) for short-term ATM options, so statement is incorrect.我觉得和表述的不是一回事，我对理解是对于theta，无论是call还是put，都小于0，ATM时|theta|最大，OTM和ITM时，with the same strike prianremaining maturity，|theta|更小。

请问C的remaining maturity不是应该是快到期的时间么？为什么里面直接把它当成两个不一样maturity的option来看了？
