A. Carcinogenic

B. Antagonistic to CO₂

C. With higher affinity for haemoglobin as compared to oxygen

D. Destructive to O₃

Answer: Option C

Solution(By Examveda Team)

Carbon monoxide is harmful to human beings as it is with higher affinity for haemoglobin as compared to oxygen.
Carbon monoxide has 210 times greater affinity for haemoglobin than oxygen. A small environmental concentration will thus cause toxic levels of carboxyhaemoglobin.
This interferes with oxygen delivery to the body's organs. The most common effects of CO exposure are fatigue, headaches, confusion, and dizziness due to inadequate oxygen delivery to the brain.
