Answer: A.) natural gas
Natural gas is the resource which can be located by the technologies like seismic, sonar and satellite technologies. The seismic wave are transferred into the suspected site and the sensors record the reflected back waves from the earth. These sensors detect the presence of natural gas. Sonar uses the principle of echo in this method the sound waves are send underwater to locate the natural gases present below the earth crust. Satellite technology uses the principle of remote sensing in which the land surveying occurs and here also the sensors detect the presence of natural gas.
