The incomplete combustion of firewood in homes produce a poisonous gas X .When inhaled gas X combines with substance 'Y' present in blood and reduces the capacity of blood to carry gas 'Z' causing respiratory problems Identify X,Y and Z

Options

A. `{:(X,Y,Z),("Carbon -mono -oxide","Oxygen","Carbon di -oxide"):}`
B. `{:(X,Y,Z),("Carbon -di -oxide ","Water","Carbonic Acid"):}`
C. `{:(X,Y,Z),("Carbon -mono -oxide ","Haemoglobin","Oxygen"):}`
D. `{:(X,Y,Z),("Carbon -di -oxide ","Blood Platelets","Oxygen"):}`

Answer

C

Explanation

The incomplete combustion of firewood in homes produces a poisonous gas called carbon mono -oxide .When carbon mono -oxide is inhaled , it combines with haemoglobin present in blood .This combination reduces the capacity of blood to carry oxygen , causing respiratory problems.
