Answer:
The correct answer is C which is Naptha
Explanation:
naphtha, any of a variety of volatile, highly flammable liquid hydrocarbon mixtures used primarily as solvents and thinners and as feedstocks for conversion to gasoline. Naphtha was the name originally used for the more volatile types of oil flowing from the ground in the Baku district of Azerbaijan and Iran. Already in the 1st century AD, the Greek writer Dioscorides and the Roman writer Pliny the Elder mentioned oil. Alchemists used the word mainly to distinguish various low-boiling mobile liquids, including certain ethers and esters.
In modern usage, the word diesel is usually accompanied by a distinguishing prefix. Coal naphtha is a volatile commercial product obtained by the distillation of coal tar. Shale oil is obtained by distilling crude oil produced from bituminous shale by destructive distillation. Petroleum naphtha is the name used primarily in the United States for a petroleum distillate containing mainly aliphatic hydrocarbons and boiling higher than gasoline and lower than kerosene.
