Answer:

b) Stage 2

Explanation:

Muscle activity decreases in Stage 2 and conscious awareness of the outside world fades. Brain waves are mainly in the theta wave range but sleep spindles (short bursts of brain activity) and K-complexes (unique and brief waveforms) occur to protect sleep and suppress outside stimuli.
