Answer:
Option B, The population has increased and so had demand for energy resources
Step-by-step explanation:
Option A is incorrect – The decrease in population causes the decreases in the number of consumers of any energy resource and thus the demand for energy resource also decreases. Therefore the "process of fracking" also reduce.
Option B is correct – With the increase in population, the number of heads consuming the energy also increases which ultimately leads to rise in demand for energy and the "process of fracking"
Option C is incorrect – If the population is rising, the resource consumption will increase and there is no reason to believe that rising population will cause decrease in resource consumption.
Option D is incorrect – If both population and demand for energy has fallen down then the “process of fracking” shall also fall down.
Option B is correct
