The correct answer is butane.
Butane is a colorless, odorless gas that is commonly used in cigarette lighters. It is also used in lighter fluid, camping stoves, and other portable fuel-burning devices. Butane is a hydrocarbon, which means that it is made up of hydrogen and carbon atoms. It is a relatively safe gas, but it can be flammable if it is not used properly.
Methane is a colorless, odorless gas that is the simplest hydrocarbon. It is the main component of natural gas and is also produced by the decomposition of organic matter. Methane is a greenhouse gas and is a major contributor to climate change.

Radon is a radioactive gas that is produced by the decay of uranium. It is a naturally occurring gas and is found in the air, soil, and water. Radon can be a health hazard if it is inhaled in high concentrations.
In conclusion, the gas emerged through the cigarette lighter is butane. It is a colorless, odorless gas that is commonly used in cigarette lighters. It is also used in lighter fluid, camping stoves, and other portable fuel-burning devices. Butane is a hydrocarbon, which means that it is made up of hydrogen and carbon atoms. It is a relatively safe gas, but it can be flammable if it is not used properly.
