I would go with A. Explanations can be found in discussions you have already posted...

I am no expert but here are my 2 cents..
I selected A initially but after checking the OA i felt that i did a mistake while choosing A..
IMO In A 'it' clearly refers to improved efficiency.. what is ambiguous here is "thereby boosting". Who is boosting the consumption, the prices, the demand or the improved efficiency..?
this problem is solved in B by including "which" that clearly refers to "prices"..

I think B suffers from parallelism error as well, see the senses increasing, lowering, boosting.

as for as referrant to which is concerned I do not think it only refers to prices as prices is tied up with demand using and.

imo A

bumping this thread to get some experts insight with this problem. Thanks in advance.

The OA shocked me. What is the source of this?

Good Question !! I'll go with 'A'...!!

IMO: B

With answer choise A, there exists a confusion with the usage of "it"....

Choice B elimates this with "demand".....

i will choose B over A...had there been no thereby in choice A..i would have selected A...

it in choice A clearly refers to improved efficiency ....it refers to the subject of preceding clause...

in choice B, "which" replaces to what? ans is it the verb:"boost" in the right form?

boost is in the correct form...

it will stimulate demand because of x and y, which boost consumption {x and y boost consumption}

I am not an expert but still IMHO it should be A.
My reason would be ->active speech used in A "it will stimulate demand" where as it is passive in B "demand will be stimulated".....Also, "GMAT" generally don't like to eat passive vegetables

Was going through this..Yet no clear answer.
Could any1 explain why A is Incorrect?
