Which of the following can serve as an alternative for acetylene?

Butane
Hydrogen
Nitrogen
Oxygen

The correct answer is: Butane

Butane is the correct answer as it can be used as an alternative for acetylene. Butane can be used as a fuel gas in welding and cutting torches, which is similar to the function of acetylene. Acetylene is a common fuel gas used for welding, cutting and brazing, but it is also expensive and unstable. Hydrogen, Nitrogen, and Oxygen are incorrect answers as they are not suitable alternatives for acetylene. Hydrogen is a flammable gas and requires oxygen to burn, while Nitrogen is an inert gas and does not support combustion. Oxygen can be used for cutting and welding, but it is not a fuel gas and therefore, not a suitable alternative for acetylene.
