The oxygen carrying capacity of blood is reduced due to binding of haemoglobin with
Show Hint
Carbon monoxide poisoning is dangerous because CO binds to haemoglobin with much greater affinity than oxygen, blocking the transport of oxygen.

- SO\(_2\)
- CO
- CO\(_2\)
NO\(_2\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Carbon monoxide (CO) binds with haemoglobin more effectively than oxygen, forming carboxyhemoglobin, which reduces the oxygen-carrying capacity of blood.
Thus, the answer is CO.
