Which of the following gases is considered to be flammable:

  1. Acetylene

  2. Argon

  3. Carbon Dioxide

  4. Helium

The correct answer is: Acetylene

Acetylene is considered to be flammable. Acetylene is a colorless, highly flammable gas with a wide range of industrial applications, particularly in welding and cutting metals. It is important to handle acetylene with caution due to its highly flammable nature. Argon, carbon dioxide, and helium are not considered to be flammable gases. Argon and helium are inert gases that do not readily undergo chemical reactions, while carbon dioxide is not flammable but can act as a fire suppressant in certain applications.
