Solution

The correct option is C Concentration of $C O_{2}$ and $H^{+}$ ions
Respiratory rhythm centre is a specialised centre present in the medulla of the brain which is primarily responsible for the regulation of respiration. A chemosensitive area situated adjacent to the rhythm center is highly sensitive to change in $C O_{2}$ and hydrogen ion concentrations in blood. Increase in $C O_{2}$ and $H^{+}$ ions stimulate this centre, which in turn stimulate the rhythm centre to make necessary adjustments in the respiratory process by which these substances can be eliminated.
