Which one of the following, if true, most supports the environmentalists' proposal?

1. A. The engines of some automobiles now on the road bum diesel fuel rather than gasoline.
2. B. Several large research efforts are under way to formulate cleaner-burning types of gasoline.
3. C. In some regions, the local economy is largely dependent on industries devoted to the production and distribution of automobile fuel.
