    A)  shallower and slow

    B)  there is no effect on breathing

    When\[C{{O}_{2}}\]concentration in blood increases breathing becomes faster and deeper. The effect of increased\[C{{O}_{2}}\]is to decrease the affinity of haemoglobin for\[{{O}_{2}}\]. Thus due to Bohrs effect the\[C{{O}_{2}}\]released in respiring tissue accelerates the delivery of oxygen by faster and deeper breathing.
