    Ans: c
    Why can't option b be the answer?

    After taking a long deep breath, breathing is stopped for sometime because pneumotaxic centre switches off breathing?

    Or do the peripheral centres and chemosensitive area in medulla oblongata sense the less amount of CO2 in blood & signal the respiratory rhythm centre to stop breathing for sometime? Please explain.

    The respiratory center is located bilaterally in the medulla and pons. Three major centers contribute to respiratory regulation. The dorsal respiratory center is mainly responsible for inspiration, the ventral respiratory center is responsible for both expiration and inspiration, and the pneumotaxic center helps control the breathing rate and pattern
