Stock levels for domestic crude oil are far lower than in past years, leaving domestic oil prices vulnerable to any hints of oil supplies being disrupted in the Middle East or to any unexpected consumer demand growth possibly prompted by colder-than-normal temperatures.

(A) leaving domestic oil prices vulnerable to any hints of oil supplies being disrupted in the Middle East or to any unexpected consumer demand growth possibly
(B) leaving domestic oil prices vulnerable to any hints of oil supply disruptions in the Middle East or any unexpected growth in consumer demand that might be
(C) leaving domestic oil prices vulnerable to any hints of oil supplies that are disrupted in the Middle East or to any unexpected growth in consumer demand as was possibly
(D) resulting in the fact that domestic oil prices are vulnerable to any hints of oil supplies
being disrupted in the Middle East or to any unexpected consumer demand growth possibly
(E) resulting in the fact of domestic oil prices that are vulnerable to any hints of oil supply disruptions in the Middle East or to any unexpected growth in consumer demand that might be

正确选项是B

请问：
平行结构中不是不能省略连词、副词和介词吗？这里or后把to省了为什么还对呢？

好吧，我明白了：
在平行结构中其它介词不可省，但是to是个特例，to …, and … 优于to … , and to …

prep上说：
该句中的并列结构vulnerable to any…or to any和vulnerable to any… or any表达都正确, 第二个to和第一个to功能一样,可以省略
