Carbon exists in the atmosphere in the form of-

Correct option is D

The correct answer is (d) Carbon monoxide in traces and carbon dioxide.
· In the atmosphere, carbon exists primarily as carbon dioxide (CO₂), which is a significant component involved in the greenhouse effect and global climate regulation.
· Additionally, carbon monoxide (CO) is also present in the atmosphere, but only in trace amounts, mainly from sources such as incomplete combustion of fossil fuels.
Information Booster:
· Carbon dioxide is a major greenhouse gas produced by natural processes like respiration and human activities, such as burning fossil fuels.
· Carbon monoxide is produced in smaller quantities, often from vehicle emissions, wildfires, and industrial processes.
· These carbon compounds play different roles in the atmosphere, with CO₂ being crucial for photosynthesis and CO being a toxic gas at higher concentrations.
