which was the case .... which 形容前面那个词，句子意思应该是需要形容前面一整句平行结构 not by , but by
如果是 was not produce by ... but was produce by 此处 was produce 可以省略，属于不够简洁

as was the case 指一句话
which :company

D项was not produced by，not指的是produced，也就是说可能不是produced，而是bought这样。而原意是说不是通过某公司生产的，否定的点在于company。第二，D的which，指代的是company，不对。应该是produced by company这件事，所以既然没有doing ，就可以用 as was the case来指一句话。

was produced not by...but by
was not produced by ...but produced by
1.not的位置不用纠结不重要，关键是平行
2.as is the case “通常情况下”
eg:As is often the case,humans are the primary cause of extinction.
as is (often) the casse with sth/sb.或者as is (often) the casse in someplace
eg:It's important to search for trials before starting treatment if standard treatment is not effective,as is the case with advanced cancers.
