Answer: C next to a water source, such as a lake or river
Step-by-step explanation:
Fracking refers to the use of water (sometimes mixed with chemicals) to fracture rocks and release the gases and oil trapped in or by the rocks. The process is to blast the rocks with highly pressurised water thereby breaking them apart.
This process requires a lot of water and so it would be more beneficial to set up a fracking site next to a water source so as to have readily available water resources.
