Carbon dioxide is linked with which gas group?

Answer and explanation

Correct answer: Greenhouse gas

The direct answer is C: greenhouse gas. Carbon dioxide, written as CO₂, is a greenhouse gas because it can absorb and re-emit part of the infrared heat that Earth’s surface gives off. This property is part of the natural greenhouse effect, which helps keep Earth warm enough for life. However, human activities such as burning coal, oil, and gas can increase the amount of carbon dioxide in the atmosphere. A larger concentration can strengthen warming and contribute to climate change. Option A is wrong because oxygen is a different gas and supports respiration and combustion. Option B is wrong because carbon dioxide is not classified as an inert gas. Option D is wrong because ozone is a different molecule, O₃, although ozone can also take part in atmospheric processes. Memory cue: CO₂ holds heat, so remember it as a greenhouse gas.
