(A) The partial pressure of carbon dioxide $(pCO_2)$ in different parts is as follows:$1$. Atmospheric air: The $pCO_2$ is approximately $0.3 \, mm\, Hg$ $(P-III)$.$2$. Tissues: The metabolic activity in tissues produces $CO_2$, leading to a higher $pCO_2$ of $45 \, mm\, Hg$ $(Q-II)$.$3$. Oxygenated blood: The blood leaving the lungs has a $pCO_2$ of $40 \, mm\, Hg$ $(R-I)$.Therefore, the correct matching is $(P-III), (Q-II), (R-I)$.

Select the correct option:
$(1)$ The respiratory rhythm center for breathing regulation is located in the medulla oblongata of the brain.
$(2)$ Each hemoglobin molecule can carry a maximum of $4$ molecules of $O_2$. (Note: The original question mentioned $CO_2$,which is incorrect; hemoglobin primarily transports $O_2$.)
