Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were last year.
(A) Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were
(B) Heating-oil prices are expected to rise higher this year over last because refiners pay about $5 a barrel for crude oil more than they did
(C) Expectations are for heating-oil prices to be higher this year than last year’s because refiners are paying about $5 a barrel for crude oil more than they did
(D) It is the expectation that heating-oil prices will be higher for this year over last because refiners are paying about $5 a barrel more for crude oil now than what they were
(E) It is expected that heating-oil prices will rise higher this year than last year’s because refiners pay about $5 a barrel for crude oil more than they did


A选项里不是应该是今年的价格和去年价格比较么？那么last year‘s 为什么不可以。
D选项 it is 结构不是更加清晰么 避免头重脚轻，wordy 如何解释？
求指教~

D中的EXPECTATION没有EXPCTED简洁。
this year与last形成工整的对仗，且不会造成歧义，因为只是同一个Heating-oil prices在今年与在去年的比较，没有必要用last year's或者that。
且last year's与this year形势上不够对仗。
D中，it的用法不对，it一般只作为形式主语放在句首，而D E中it均不是形式主语且没有指代对象，是歧义。

可参考OG在C、E选项的说明
the  possessive year's is not parallel with the adverbial phrase this year

在本题中，是同一样物品（price）在不同时间（分别以last year 与 this year俩副词短语表示）的比较
