Which of the Following Statements BEST Explains Why Increasing Administered

Which of the following statements BEST explains why increasing administered oxygen should be done cautiously in a patient with severe chronic obstructive pulmonary disease (COPD) AT REST?

A) The body may rely on hypoxic drive to breathe (oxygen receptors) and increasing administered oxygen at rest leads to hyperoxemia suppressing the hypoxic drive.
B) The body needs additional time to allow the peripheral chemoreceptors to cause an increase of ventilatory rate to improve oxygenation.
C) The body is relying on carbon dioxide to regulate the respiratory cycle,and increasing administered oxygen at rest leads to inhibition of the carbon dioxide receptors.
D) Increasing administered oxygen to the body oversaturates the system leading to toxicity.
