Presence of nitrogen in high concentration in contaminated air reduces
partial pressure of oxygen in lungs, thereby causing asphyxia (suffocation)
leading to death from oxygen deficiency. Concentration of N2
in
contaminated air at which it acts as a natural asphyxiate is ≥ __________
percent.
(A) 84
(B) 88
(C) 80
(D) 92
