Answer: Option A

Solution(By Examveda Team)

The most effective in warming atmosphere is CO₂.
Greenhouse gases like CO₂ absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Global warming would reach 2.1°C to 3.5°C, and 3.3°C to 5.7°C under the very high GHG emissions scenario.
