Answer: Option D

Solution(By Examveda Team)

Hydrogen is not a greenhouse gas.
A greenhouse gas (GHG or GhG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (H₂O), carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O) and ozone (O₃).
Hydrogen does not have a direct effect on climate. Instead, it affects other pollutants like methane which is a prominent greenhouse gas.
