A. on both diesel fuel and diesel engines has sparked a counterattack by the oil industry, saying

B. on both diesel fuel and engines have sparked the oil industry to counterattack, and they say

C. on both diesel fuel and diesel engines has sparked a counterattack by the oil industry, which says

D. both on diesel fuel and engines has sparked the oil industry to a counterattack, saying (C)

E . both on diesel fuel and diesel engines have sparked the oil industry to counterattack, and it says

My answer A

我觉得C中的which指代会有歧义，而saying的主语就是主句主语是完全没有歧异的。

应该是C,which歧义是什么呢？

A用saying逻辑意义不合理，使石油产业声称，不是整个句子的内容声称

不是说which不可以指代前面整个句子吗?虽然也知道A有问题,但是我还是选他了.

which 指代oil industry.

恩，应该选C，句子逻辑意思还是很重要的。
