Which of the following most accurately describes the brain during sleep?
a. the brain goes dormant and does not emit brain waves.
b. the brain remains active and emits brain waves.
c. the brain goes dormant and emits brain waves.
d. the brain remains active and does not emit brain waves.

The correct answer is B) The brain remains active and emits brain waves.

The brain remains active during sleep time and it emits different brain waves ( like theta wave, alpha wave) through different stages ( like NREM- Non rapid eye movement and REM- rapid eye movement stage)

During sleep, the cells of the body are re-energised and the toxins are removed from the brain.
