Hi Sravya,
Good question. We're not comparing two sets of prices, actually. Heating oil prices are expected to be higher THIS YEAR than LAST [year]. "this year" and "last" are actually adverbial -- telling us WHEN prices are expected to be higher. We're comparing the two time periods, not the prices.

"This year's prices are expected to be higher than last year's." THEN we would be correctly comparing two sets of prices.

Answer choice B if you check OG it says 'pay' and not paying, so we cant dismiss it based on 'did'. I can see rise higher is redundant.
I still dont get the OG explanation 'more than' should immediately follow \$5 a barrel - why is this?
