support A

first, in A, it = efficiency based on singular form

second, in B, which cannot stand for a whole sentence, and the passive form "by ..." does not have the excecutive part.

我选了A，为什么我做的题目给的答案是B？

b 的which太不像正确答案了

a里的therby + doing 被选中几率很高

望有nn，权威说明下答案

这题到底标准答案选什么?我手里的答案是B,但我还是觉得A对.

agree A.

"which" in B is illogic to refer increasing supply and lowering prices

support A
