When a man inhales air containing normal concentration of ${O_2}$ as well as $CO$ he suffers from suffocation because
A
$CO$ reacts with ${O_2}$ reducing its percentage in air
B
Haemoglobin combines with $CO$ instead of ${O_2}$ and the product cannot dissociate
C
$CO$ affects diaphragm and intercostal muscles
D
$CO$ affects the nerve of the lungs
(AIIMS-1993)
