Which of the following is a gaseous combustible?

Explanation:
A gaseous combustible is a gas that can burn in air to release energy. Acetylene fits this as a fuel gas commonly used in welding; it burns with oxygen to produce a hot flame capable of melting metal. Oxygen, while essential for combustion, is not a fuel itself—it is an oxidizer that helps other fuels burn. Water is not flammable; it is the end product of combustion in many reactions. Nitrogen is inert and does not burn.
