Answer: (A)

Verified step by step guidance

1. Understand the different stages of sleep: Sleep is divided into REM (Rapid Eye Movement) and non-REM stages. Non-REM sleep is further divided into stages N1, N2, and N3.
2. Identify the characteristics of each sleep stage: REM sleep is associated with vivid dreams, while non-REM sleep, particularly stage N3, is known as deep sleep and is characterized by slow-wave activity.
3. Learn about night terrors: Night terrors are a type of parasomnia, which are disruptive sleep disorders that occur during arousals from non-REM sleep, typically during the first third of the night.
4. Determine when night terrors occur: Night terrors usually happen during deep non-REM sleep, specifically during stage N3, which is the deepest stage of non-REM sleep.
5. Eliminate incorrect options: Since night terrors occur during deep non-REM sleep, they do not occur during REM sleep, N1 stage, or microsleeps, which are brief episodes of sleep lasting only a few seconds.
