A Correct answer
Explanation

Nitrogen (N2) was named 'Azote' by Antoine Lavoisier, derived from Greek 'a-' (without) and 'zoe' (life), meaning 'lifeless'. This was because nitrogen does not support combustion or respiration. CO2 is carbon dioxide, H2 is hydrogen, and Xe is xenon - none were given this name by Lavoisier.
