Sure, let's analyze the options step by step to determine which gas is vital in maintaining atmospheric temperature.

1. Oxygen (O₂):

   • Oxygen is essential for respiration in most living organisms and is a significant component of the atmosphere. However, it is not the primary gas responsible for maintaining atmospheric temperature.

2. Carbon Dioxide (CO₂):

   • Carbon dioxide is a greenhouse gas, which means it traps heat in the atmosphere. This trapping of heat is crucial for maintaining the Earth's temperature and making it habitable. CO₂ plays a significant role in the greenhouse effect, which helps to regulate the Earth's temperature.

3. Nitrogen (N₂):

   • Nitrogen makes up about 78% of the Earth's atmosphere and is essential for the growth of living organisms. However, it is relatively inert and does not significantly contribute to the greenhouse effect or the regulation of atmospheric temperature.

4. Nitrogen Dioxide (NO₂):

   • Nitrogen dioxide is a pollutant and a component of smog. It can contribute to atmospheric warming but is not the primary gas responsible for maintaining atmospheric temperature.

Based on this analysis, the correct answer is:

b. Carbon Dioxide
