哈哈，看来大家都很厉害。虽然还差一个到5位，大家都如此一致，就破例吧。如果有纠结于A和C之间的童鞋，请阅以下的讲解（此题是在blog上当经典例题讲的）：

“C和A的区别是啥？就是say这个动作到底是industry发出，还是全句的主语proposal 发出。这个时候不能根据A认为是saying，就把其它选项杀掉，而应该根据全句的句意，判断说出这话的应该是industry，因为proposal不会自己反对自己，只有石油工业才会反对那个限制柴油机使用的proposal。这背后的判断标准是什么？就是传说中的逻辑，动作发出者与动作的合理对应。”

摘录一段RON的解答，回答的太好了:

choice (a) uses a COMMA + -ING modifier -- a very common construction -- and uses it incorrectly.

the short version:
COMMA + -ING modifiers modify the ENTIRE PRECEDING CLAUSE (including the subject of that clause).

the long version:
see here
post30766.html#p30766

...so, according to this COMMA + ING modifier, it is actually "The Environmental Protection Agency’s proposal" that is "saying that the move will exacerbate the nation’s fuel supply problems", while (or because of) sparking a counterattack by the oil industry.

that doesn't make sense.

re: (c)

actually, "which" should indeed refer to the oil industry, because the oil industry is saying that the proposal will exacerbate the nation's fuel supply problems.
this is a response to the proposal, not the content of the proposal itself.

so, "which" is used totally correctly here.
