Answer 2

Answer: Coal

Step-by-step explanation:

Coal comes under the category of fossil fuels which takes millions of year to form. But now a days the use of coal is being increasing because of more and more agricultural and industrial setup.

The amount at which the coal is forming is slower than the amount at which it is being used is much higher.

Hence, in the next 20 years there is a less chance the formation of coal will be more than its use. So, the least growth can be seen in coal.
