A) K complexes
B) sleep spindles
C) REM
D) beta waves
K Complexes
A type of brainwave that appears during Stage 2 of sleep, signifying periods of brain silence or reduced neural activity.
Sleep Spindles
These are brief bursts of brain activity characterized by their waxing and waning appearance on an EEG, typically occurring during stage 2 of sleep.
Stage 2 Sleep
A period of light sleep before entering deeper sleep, characterized by specific patterns such as sleep spindles and K-complexes.

Final Answer :
B
Explanation :
The rapid brain-wave activity bursts that last 1 to 2 seconds and occur in stage 2 sleep are called sleep spindles. K complexes are sudden, sharp waveforms that occur in response to external stimuli during stage 2 sleep. REM (rapid eye movement) is a stage of sleep characterized by vivid dreams and rapid eye movements. Beta waves are high frequency, low amplitude brain waves that are associated with an alert, awake state.
