A new genetically engineered papaya was produced not by seed companies who have been motivated by profit, which was the case with most genetically modified crops previously approved for commercial use, but university and United States Department of Agriculture researchers who allowed growers to use it free of charge.

(A) produced not by seed companies who have been motivated by profit, which was the case with most genetically modified crops previously approved for commercial use, but

(B) produced not by profit-motivated seed companies, the case with most genetically modified crops previously approved for commercial use, but

(C) produced not by profit-motivated seed companies, as was the case with most genetically modified crops previously approved for commercial use, but by

(D) not produced by profit-motivated seed companies, which was the case with most genetically modified crops previously approved for commercial use, but was produced by

(E) not produced by seed companies who have been motivated by profit, the case with most genetically modified crops previously approved for commercial use, but by

这道题目的答案是C，我想问一下B选项的the case with在这里为什么错了呢？解释中说这里的插入语the case with表达意思不清楚，谢谢大家。

(C)
produced not by profit-motivated seed companies, as was the case with
most genetically modified crops previously approved for commercial use,
but by
另外，C中的as was the case with
most genetically modified crops previously approved for commercial use怎么理解好呢？--（profit-motivated seed companies）作为这个一样例子在大多数情况下生产此前被认为有商业用途的基因改良玉米
