问题补充：

Victor apologized for to inform me of the change in the plane.

A. his being not able

B. him not to be able

C. his not being able

D. him to be not able

答案：

A. his being not able

B. him not to be able

(答案→)C. his not being able

D. him to be not able

解析：考察动名词复合结构。For是介词，后面要接动名词，本题是动名词的复合结构，所有格+动名词，其否定形式是在动名词前面加not,故C正确。句意：Victor为他没有告知我飞机的改变而向我道歉。
