Evaluate the correctness of the following statement: If a person breathes in and out rapidly for some time (hyperventilation), his body allows him to hold his breath for a longer period than in the case of normal ventilation(for example when he is submerged in water). Is that due to (i) increase in O2 levels in his body (ii) decreased level of CO2 in his body at that time?
