Solution

The correct option is C
More CO₂ concentration in blood

An increase in the carbon dioxide concentration in the blood stimulates the inspiratory and expiratory centres through increased formation and dissociation of carbonic acid and increased concentration of H⁺, which lowers the pH of blood and results in acidosis.
