C) narcolepsy.
D) sleep apnea.
<u>Correct Option:</u>

Option: D
<u>Explanation:</u>
Sleep apnea is a disorder which is identified by frequent stoppage and breathing start while sleeping. This is due to extreme relaxation of the throat muscles that hinder the normal breathing mechanism leading to reduced blood oxygen levels (recognized as hypopnea).
Throughout a sleep study, the patient's oxygen level is tracked with a pulse oxymeter connected to the hand, finger as well as other parts of the patient. An individual with SA will get a decreased amount of air in inhalation due to irregular breathing patterns while asleep.
