a) True
b) False

Answer 1

Hint: The Petroleum is black in colour when the crude oil is extracted beneath Earth and it is yellow in colour like gold after refining. Petroleum is equally valuable to gold because of its properties.

Complete answer:
The petroleum is a liquid that occurs naturally beneath the earth surface. We extract it below the earth. The fossil fuel we use these days to whom we refer petrol is the refined oil of petroleum. The liquid that is extracted undergoes various processes of extraction and purification. After all the process, we get many components which are commercially very valuable.
So, yes; the petroleum is known as black gold. This statement is true.
Now, let us see the reason for this.
The Petroleum is called black gold because when the crude oil is extracted from the soil below, it is black in colour. Petroleum is very expensive like gold. Comparing its high value with gold in terms of properties and moneywise; it is regarded as black gold. Many components of crude oil have commercial importance. It is even found rare on Earth and further, its extraction requires a lot of expenses.
But after the purification of black crude oil, it gives golden colour. So, this is another reason for its name.

Therefore, the given statement is true. Option (a) is correct.
