Option D is correct.

The Marcellus shale is: a major new source of gas that has become available because people developed the technological tools to recover the gas.

Explanation:

The largest natural gas-producing region in the United States, accounting for close to one-fifth of the country's total gas production is the Marcellus shale.

This shale has emerged as one of the most cost-effective gas plays, given the high production rates of wells in addition to improving drilling efficiencies being brought about by the appropriation of technologies such as pad drilling.
