PREP-2-52, 对于这个结构的困惑

The two oil companies agreed to merge their refining and marketing operations in the Midwest and the West, forming a new company for controlling nearly fifteen percent of the nation's gasoline sales.

(A) forming a new company for controlling

(B) forming a new company that would control

(C) which would form a new company that controlled

(D) which formed a new company for controlling

(E) which formed a new company that would control

答案一看就知道不是A 就是B ， 但是答案是B ，我选择了A ， 请问各位牛牛为什么是A对阿， 是应为FOR不能表示目的吗。 请指教了

大家没有人理我555

做题的时候我选的是B。没有考虑太多，因为即使是表面目的的for doing也不是一种优选的结构，一般都是不定式表示被动。而这题其实也没有表目的的意思
