The correct option is B (i) $C O_{2}$ (ii) $H^{+}$ (iii) rhythm centre
Receptors associated with aortic arch and carotid artery can recognise a change in $C O_{2}$ and $H^{+}$ concentration and send necessary signals to the rhythm centre (medulla oblongata) that controls the rate of breathing.
So, the correct answer is (B).
