B.as a method of the extraction of minerals well established

C.was a well-established method of mineral extraction

D.was a well-established method of extracting mineral that was

E.had been a method of mineral extraction, well established
为什么选c呢？？是因为简洁吗，可是as early as 之前总觉得应该加well established,请教中。。。

一般A of B形式，主语在于A，后面的修饰部分就是修饰A吖~~~
C中前面已经有了a well-established method，还要well established干嘛~
