标题: discriminate A from B vs. discriminate between A and B

After a few weeks' experience, apprentice jewelers can usually begin to discriminate, though not with absolute certainty, genuine diamonds from imination dismonds.

(A) genuine diamonds from imitation diamonds

(B) genuine diamonds apart from imitations

(D) among genuine diamonds and imitation diamonds

(E) whether diamonds are imitation or genuine.

Since discriminate A from B and discriminate between A and B means the same thing, why choose C not A?

This quesion is a problematic one since according to the dictionary, both discriminate A from B and discriminate between A and B are correct and express the same meaning.

discriminate A from B应该是将一个事物从另一个事物中辨别出来，B通常应该是个比A大的集合；

discriminate between A and B 应该区别两个事物，两个事物可通常不是集合大小的关系。

我查的字典是牛津的，上面是这样说的

discriminate between A and B 表示区别、辨别，没有提到discriminate A from B的用法

discriminate against/in favor of 表示歧视

Even dictionaries are not consistent.

Even if that is the case, then how we can we identify the relationship between A and B?

e.g. Discriminate right from wrong (from dictionary)

Discriminate genuine D from fake D (we can still take this as identify Genuine D from fake D)

I really think both A and C are right.
