The missing options are;
A) His circadian rhythm has been disrupted.
(B) His stages of sleep are out of order.
(C) His delta waves have lost significant
amplitude.
(D) He has narcolepsy.
(E) He is experiencing REM rebound.
Option A is the correct option.
- Option A; This is the likely explanation for him still feeling lethargic because circadian rythm is the internal clock of the human body that regulates the sleep-wake cycle. And when it is faulty, it results in a sleep disorder.
- Option B; This is not correct because stages of sleep has nothing to do with feeling lethargic after sleeping for several hours.
- Option C; This can't be the cause because delta waves are produced in deep sleep and they help in relaxation of the brain when sleeping. Thus they have nothing to do with feeling lethargic.
- Option D; Narcolepsy is a diseased condition where people fall asleep at wrong times. Again this doesn't have any effect on feeling lethargic after sleeping for several hours.
- Option E; REM Rebound is when one receives more sleep than they usually get. This has no impact on feeling lethargic.
