Fill up the blanks in the following paragraph by selecting the correct option. Human beings have a significant ability to maintain and moderate the respiratory rhythm to suti the demands of the body tissues. This is done by the neural system. A specialised centre present in the medulla region of the brain called `overset((i))"_______"` is primarily responsible for this regulation. Another centre present in the pons region of the brain called `overset((ii))"_______"` can moderate the functions of the repiratory rhytm cenre. Neutral signal from this cenre cen reduce the duration of `overset((iii))"_______"` and thereby alter the respiratory rate. A `overset((iv))"_______"` is situated adjacent to the rhythm centre which is highly sensitive to `CO_(2)` and hydrogen ions.A. `{:("(i)",(ii),(iii),(iv)),("Chemosensitive area","Respiratory rhythm centre","Expiration","Pneumotaxic centre"):}`B. `{:("(i)",(ii),(iii),(iv)),("Respiratory rhythm centre","Pneumotaxic centre","Inspiration","Chemosensitive area"):}`C. `{:("(i)",(ii),(iii),(iv)),("Respiratory rhythm centre","Chemosensitive area","Expiration","Pneumotaxic centre"):}`D. `{:("(i)",(ii),(iii),(iv)),("Pneumotaxic centre","Chemosensitive area","Inspiration","Respiratory rhythm centre"):}`
