Which of the following is a non renewable resource?
A. Forest
B. Coal deposit
C. Water
D. Wild life

Hint: A resource which is having high economic importance but cannot be replaced naturally at a pace that matches its rate of consumption is known as the non-renewable resource.

Complete answer:
Nonrenewable resources can be of four major types namely, natural gas, nuclear energy, coal and oil. These are together termed as fossil fuels. Fossils fuels as the name suggests, were formed from the dead animals and plants buried within the earth over millions of years ago.
In this process, the original organic material turns into fuels like gas or oil under continuous heat and pressure. Besides fossil fuels (for example coal, petroleum, natural gas), the metal ores and earth minerals, groundwater in some aquifers are also deliberated as a non-renewable resource. Also, the fossil fuels are not sustainable and they are formed in billions of years therefore they are considered as nonrenewable resources.
Thus, the right option is B.

Note: Nuclear energy, oil and natural gas are considered as the non-renewable sources of energy. They cannot be readily replaced after their consumption as their formation takes a long duration of time. But these resources are of great economic importance as they supply the majority of energy needs. Coal is a fossil fuel in solid form. It can be used for power plant generation and for warming homes as well. They are found buried in the sedimentation layers. The coal being solid cannot be extracted like natural gas or the crude oil. The coal needs to be excavated up from the ground.
