Answer:
A. Natural gas well
Step-by-step explanation:
The hydrogen is a gas that can be found in numerous places on Earth, as it is found in all of the spheres. The water has it as one of the two chemicals that make it, it can be found in solid quantities in the atmosphere, as well as in the lithosphere. One place where this gas can not be found is a natural gas well. The natural gas is a fossil fuel, but it doesn't have hydrogen in its composition. This gas is mostly made out of methane, with smaller percentages of ethane, propane, butane, and pentane. If the situation is that the natural gas is almost entirely composed of methane, then it is considered to be a dry gas.
