उत्तर
Carbon exists in the atmosphere in the form of carbon monoxide in traces and carbon dioxide.
Explanation:
Carbon primarily exists in the atmosphere as carbon dioxide (CO2) in the air (approximately 0.04%). Carbon monoxide (CO) is also present, but only in trace amounts, mainly as an air pollutant from sources like incomplete combustion. Therefore, the most accurate description is that the atmosphere contains both CO2 and trace amounts of CO.
