The correct statement that apply to hydraulic fracturing is

d.

Explanation:

a. Hydraulic fracturing allows geologists to capture natural gas stored in the pore spaces of shale.

Correction; The geologist identifies the likely location of new oil and gas deposits which are subsequently developed and by hydraulic fracturing we mean a drilling method for the commercial production of petroleum energy resources that involves the high pressure introduction of fluids for fracking into the well in shale oil and gas reservoir to form passageways or cracks for the free flow of petroleum.

b. Once the shale is shattered, fractures remain open due to the inherent strength of the shale.

Correction; The fracture is kept open by proppants such as bauxite, silica sand and ceramics, which have granular to prevent the opened fractures from closing when the fracturing process ends

c. Wastewater from hydraulic fracturing is absorbed into the shale indefinitely.

Correction; A proportion (about 15 or 20 percent of the injected fracking fluid) is recovered through the well casings

d. Hydraulic fracturing threatens the supply of other natural resources.

Some natural resources issues associated with hydraulic fracturing include

Impact on ground water

Chemical spill to the environment

Wildlife disruption

Collection of sand required for fracturing

Possibility of seismic effects

Availability of water

e. Some large magnitude historic earthquakes can be traced to the use of hydraulic fracturing.

Correction It is very uncommon to find a relationship between earthquake and hydraulic fraction
