Ans: d
Explanation: All three are sources of methane. Natural gas and petroleum systems are one of the largest source of CH4 emissions. Methane is the primary component of natural gas. Some CH4 is emitted to the atmosphere during the production, processing, storage, transmission, and distribution of natural gas. Methane emissions from passenger cars (automobiles) have however dropped, as the use of catalytic converters increased. Methane is generated in landfills as waste decomposes and in the treatment of wastewater. As one of the most significant natural sources of atmospheric methane, wetlands remain a major area of concern with respect to climate change.

Sources of Methane:
Wetlands:
- Wetlands are a significant natural source of methane emissions.
- Methane is produced in wetlands through a process called anaerobic decomposition, where organic matter decomposes in the absence of oxygen.
Combustion of Fossil Fuels:
- Combustion of fossil fuels like coal, oil, and natural gas releases methane into the atmosphere.
- Methane is a byproduct of incomplete combustion and can escape into the atmosphere during extraction, processing, and transportation of fossil fuels.
Automobiles:
- While automobiles do not directly emit methane, they contribute to the formation of methane through the incomplete combustion of fuel.
- Exhaust gases from automobiles contain various pollutants that can react in the atmosphere to form methane.
Conclusion:
- All three sources mentioned in the question are contributors to methane emissions, with wetlands being a natural source, combustion of fossil fuels being a human-induced source, and automobiles indirectly contributing to methane formation.
- It is crucial to address all these sources to effectively reduce methane emissions and mitigate its impact on climate change.
