Which of the following gases is known for being colorless, tasteless, and odorless while not supporting life?

The gas recognized for being colorless, tasteless, and odorless while not supporting life is nitrogen. Nitrogen comprises about 78% of Earth's atmosphere and is an inert gas that does not support combustion or sustain metabolic processes in living organisms. While it is essential in biological systems for its role in the nitrogen cycle and as a component of proteins and nucleic acids, nitrogen itself is not utilized by animals and plants in its gaseous form.

Although the other gases listed have their unique properties and roles—oxygen is vital for respiration, carbon dioxide is a crucial part of photosynthesis, and argon is an inert gas that makes up a small portion of the atmosphere—they either support life or serve specific functions in biological systems, unlike nitrogen which is often regarded as a filler gas in the atmosphere.
