Answer:

b. pumping materials into a well deep underground

Explanation:

Fracking is one method to access natural gas and (oil) covered miles and miles underneath the Earth's surface. Amid this procedure, a gigantic drill is utilized to go through numerous layers of earth and shake that lie between the surface as the natural gas.

A special water mixture is then pumped directly at the rock miles underneath so as to discharge the gas it contains. The blend – which is principally water, sand, and certain synthetic compounds – are constrained into the stone (at incredibly high weights) so as to compel the gas out to where we can collect it. The drill can be driven into the earth either vertically or horizontally.
