Which of the following is Not a green house effect gas?

Greenhouse gases (such as Carbon dioxide (${\text{CO}}_2$), Methane (${\text{CH}}_4$), Ozone (${\text{O}}_3$), and Water Vapor) trap infrared thermal radiation in the atmosphere, warming the planet.Nitrogen (${\text{N}}_2$) makes up roughly $78\%$ of the atmosphere, but its diatomic molecular structure prevents it from absorbing infrared light, meaning it is not a greenhouse gas.
