A) NREM-1 sleep
B) NREM-2 sleep
C) NREM-3 sleep
D) REM sleep

Answer 1

The correct answer is D.

Step-by-step explanation:

The stages of sleep are divided in REM and NREM, also the NREM stages are divided in 1, 2, 3 and 4.

In stages NREM 3 and 4 occurs the deeper sleep and the person is less likely to be awaken during these stages.

In stages 1 and 2 occur the lighter sleep.

In REM stage the person is in a state very similar to the awake state and therefore is more likely to be awaken in this stage. Also, in the REM stage occur dreams.
