Which of the following is NOT a fuel produced from crude oil?

The correct answer is that plastic is not a fuel produced from crude oil. While crude oil is a primary source of many fuels used for energy, such as petrol, diesel, and kerosene, plastics are materials that are derived from petrochemicals, which are products made from the complex mixture found in crude oil.

Petrol, diesel, and kerosene are all types of fuels that are refined from crude oil through processes like distillation. These fuels are used for transportation and heating. In contrast, plastics are synthetic materials created from various petrochemical compounds, including those derived from crude oil, but they are not used primarily for fuel purposes. Instead, plastics serve a wide variety of functions in products ranging from packaging to construction materials.
