Peripheral chemoreceptors are stimulated whenever the arterial $\mathrm { P } _ { \mathrm { O } _ { 2 } }$ falls below normal, but they are not solely stimulated by this. They are also stimulated by an increase in arterial $\mathrm { P } _ { \mathrm { CO } _ { 2 } }$ and an increase in arterial H+. Therefore, statement A is incorrect.
