Answer: D. one meter in front of the source

Mercaptan is a foul smelling gas which is added to the natural gas such as butane or propane. As, the natural gas is colorless and odorless, the mercaptan is added to detect the gas. It is added to detect the leakage of the natural gas. The gas sensors are able to detect the flow or leakage of gas at various locations but the maximum concentration of the natural gas containing the mercaptan can be found in one meter in front of the source. The source exhibit maximum concentration of the natural gas along with the mercaptan.
