Despite the approach of winter, oil prices to industrial customers are exceptionally low this year and likely to remain so. Therefore, unless the winter is especially severe, the price of natural gas to industrial customers is also likely to remain low.
Which of the following, if true, provides the most support for the conclusion above?
(A) Long-term weather forecasts predict a mild winter.
(B) The industrial users who consume most natural gas can quickly and cheaply switch to using oil instead.
(C) The largest sources of supply for both oil and natural gas are in subtropical regions unlikely to be affected by winter weather.
(D) The fuel requirements of industrial users of natural gas are not seriously affected by the weather.（B）
(E) Oil distribution is more likely to be affected by severe winter weather than is the distribution of natural gas.

我觉得A是加强了
但是从原文来说从油价格低直接推理到天然气价格低是有严重逻辑漏洞的
而选项B填补了这个漏洞
所以是most support

补充：conclusion是“除非冬天特别寒冷，天然气价格会保持低价”

而A说冬天温不温和，这个事情conlusion里已经考虑到了.

换句话说，如果冬天寒冷（跟A相反），conclusion会被削弱吗？不会，因为conclusion已经考虑到这个问题.
返回来，冬天温和（不寒冷）自然就没有增强conclusion了
