OG11.0, RC-25题答案感觉很难理解？求答

题目The alignment of producers of VHS format VCRs with producers of prerecorded videotapes is most similar to which of the following?

(A) The alignment of an automobile manufacturer with another automobile manufacturer to adopt a standard design for automobile engines

(B) The alignment of an automobile manufacturer with an automotive glass company whereby the manufacturer agrees to purchase automobile windshields only from that one glass company

(C) The alignment of an automobile manufacturer with a petroleum company to ensure the widespread availability of the fuel required by a new type of engine developed by the manufacturer

(D) The alignment of an automobile manufacturer with its dealers to adopt a plan to improve automobile design

OG正确答案是C, 按照文章的意思，家庭影院系统和预先录制好的磁带之间的关系是一种互补性的关系，并且都是在两个工厂之间开展合作的，按照这个意思，答案应该选择汽车制造商与汽车玻璃生产上之间的关系才是类似关系，第一，二者是互补关系，第二，二者都是厂商。而OG给出的答案是一个生产厂商和一个石油公司之间的合作，前者是工厂，但后者并不一定，尽管二者的关系是互补关系。

按照道理，这篇文章所讲的合作关系表现为两个方面，一个是生产商之间的合作或者联盟，同时可能还有和运销、销售渠道等方面的合作。如果选答案B,那么就表示是前一种联盟关系。OG给出的答案是C, 是否意味着后一种关系，即生产者与石油公司（严格意义上是销售渠道，运销问题）的联盟？

不知道我的理解是否准备，请高手指点？
