Which company manages the distribution of CNG pipelines in Texas?

Answer: C — Texas Railroad Commission

The Texas Railroad Commission is the correct answer because it is the regulatory body responsible for overseeing the natural gas industry in Texas, including the distribution and safety of CNG (Compressed Natural Gas) pipelines. The Commission establishes rules and regulations that govern the operation of citizens involved in the transportation and distribution of natural gas, which includes ensuring that pipeline integrity is maintained and that industry practices are in compliance with state and federal laws. The other choices, while they may be energy companies or utility providers, do not have the same regulatory authority over CNG pipeline distribution as the Texas Railroad Commission. Texas Gas Service and Atmos Energy are utility companies that provide services to consumers, whereas CenterPoint Energy operates within a broader capacity as an energy delivery company, but they all operate under the regulations set forth by the Railroad Commission. The unique role of the Railroad Commission in regulating and managing aspects of CNG pipelines distinguishes it as the correct response.
