Check Answer
The correct answer is C) Coal.
Black gold is a common term used to refer to crude oil, which is a fossil fuel that is extracted from deep within the earth’s crust. The oil is typically dark in color and has a high carbon content, which is why it is sometimes called “black gold.” Oil is a valuable resource and is used to fuel many of the world’s industries and transportation systems.
On the other hand, black diamond is a common term used to refer to coal. Coal is also a fossil fuel, but it is formed from the remains of plants that lived millions of years ago in swampy environments. Over time, heat and pressure transformed the plant matter into coal. Coal is a valuable resource and is used primarily as a fuel source for electricity generation and heating. Coal is typically black in color, which is why it is sometimes called “black diamond.”
