Major airplane fuel companies are raising the price of their fossil-based fuel to encourage airliners to purchase the companies' bio-fuel, reducing harmful emissions in the long run. However, critics note that using this bio-fuel requires restructuring engines and fueling infrastructure, and so ti is unreasonable to expect airlines to start using bio-fuel in response to an increase in fossil-based fuel prices.
Considering the critics' point, which of the following if true, would best support the prediction that fuel companies will most likely succeed in reducing harmful emissions?
(A) The additional revenue from the higher-priced fossil fuels will be applied to research in to "drop-in" bio-fuel that does not require changes to existing aircraft
(B) The price increase will cause airliners to purchase fuel from other sources, making the market more competitive
(C) Because bio-fuel is a relatively recent invention, most planes currently in use are designed to use only standard fossil-based fuel
(D) Airliners can cut costs in other area in order to offset the higher cost of conventional fossil fuel
(E) The airlines that can most easily afford the newly expensive fossil-based fuel are those responsible for the most harmful emissions
