The correct option is C preventing haemoglobin to form oxyhaemoglobin
Carbon dioxide and carbon monoxide gases are emitted during
the combustion of various fuels. Carbon monoxide is poisonous, whereas
carbon-dioxide is non-toxic in nature. Carbon monoxide is poisonous because it
is capable of forming a complex with hemoglobin (carboxyhaemoglobin), which is
more stable than the oxygen-haemoglobin complex. The concentration range of
3–4% of carboxyhaemoglobin decreases the
oxygen-carrying capacity of blood. This results in headaches, weak eyesight,
nervousness, and cardiovascular disorders. A more increased concentration may even
lead to death.
Carbon monoxide when binds to hemoglobin forms a stable
compound - carboxyhaemoglobin. Since, oxygen of carbon monoxide binds more
readily to hemoglobin than do Oxygen of carbon dioxide, therefore carbon monoxide
prevents carbon dioxide from binding to Hb, which means diffusion or exchange
of gases won't take place at alveolar site. So, carbon monoxide is more harmful
because it prevents oxygen from entering the body.
