When consumers switch from diesel oil to natural gas heating, certain longer-term air pollution levels can fall, but most immediately to consumers, short-term heating costs could fall as well even though the price of heating a home with natural gas is occasionally the same as it is for oil. By installing more efficient furnaces, consumers can keep costs low even when roller-coaster oil prices rise again, as they inevitably will, not to mention that air quality could potentially improve as well.
Which of the following, if true, would most significantly undermine the argument above?
(A) Although gaining popularity, natural gas furnaces still trail diesel oil furnaces in popularity.
(B) Many natural gas burning furnaces currently in operation release more harmful matter into the atmosphere than diesel oil furnaces do.
(C) When natural gas is burned it release methane, a chemical known to affect the atmosphere.
(D) The price of natural gas typically demonstrates a pronounced positive correlation with the price of oil.
(E) Regulations prohibit the installation of new furnaces, including natural gas furnaces, without a permit.

Only thing to note in the question is the last line...
..."not to mention that air quality could potentially improve as well."
This line is there only as a fact and has nothing to do with the conclusion, which only deals with the price issue. Now let us see the options:
(A) Although gaining popularity, natural gas furnaces still trail diesel oil furnaces in popularity.
Our Statement deals with the price. So Popularity is out of scope.
(B) Many natural gas burning furnaces currently in operation release more harmful matter into the atmosphere than diesel oil furnaces do.
Our conclusion deals with the price so we are not concerned with the harmfulness of any source. Out of scope
(C) When natural gas is burned it release methane, a chemical known to affect the atmosphere.
Same as above. Out of scope.
(D) The price of natural gas typically demonstrates a pronounced positive correlation with the price of oil.
Now we are talking about price.If oil price goes up, price of Natural gas will follow. Which undermines the conclusion that natural gas will be benefical when oil prices will spiral. So B looks good.
(E) Regulations prohibit the installation of new furnaces, including natural gas furnaces, without a permit.
Not at all related. Out of scope.
B is the Answer.

I think you mistyped "B" instead of "D" in your "_ is the answer" phrase above. I think D is correct because if the price of gas goes up then it messes with the potential adoption of gas and breaks the argument. Option B attacks the evidence and latter part of the argument i.e."not to mention that air quality could potentially improve as well", which is only possible if they do adopt the gas solution.
Basically D addresses the core of the argument and B stays at the peripheral inconsequential stuff.
Please Kudos if it is explained well.
