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.

If we had:

"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?

Is it apt to just say 'heating- oil prices are expected to be higher this year than last' ? Shouldn't the than be followed by last year's ?
