• B. Nitrogen
• C. Hydrogen
• D. Carbon dioxide

Answer 1

The correct option is D

Carbon dioxide

The correct answer is D: Carbon dioxide

The explanation for Correct answer:

1. Global warming: The phenomenon of the gradual rise in the temperature of the earth is due to the high amount of emission of greenhouse gasses such as carbon dioxide, nitrogen, methane, and ozone. warm the atmosphere by efficiently absorbing the infrared radiation emitted by the earth’s surface, the atmosphere, and the clouds. As a result of the warmth of the atmosphere, it also radiates infrared radiation in all directions, including downward to the Earth’s surface. The greenhouse gasses trap this heat in the troposphere.
2. Carbon dioxide is responsible for Global warming: The greenhouse gas Carbon dioxide is not considered a pollutant, but in higher concentrations, in the Atmosphere, it makes a thick layer above the earth's surface which absorbs the radiation of the heat from the earth's surface due to which, the temperature of the earth's surface increases, and causes global warming.

Final answer: The correct answer is an option (D)
