B
growth hormones that occur during sleep
C

Explanation: 

Detailed explanation-1: -In the brain, a small group of hypothalamic nerve cells, the suprachiasmatic nucleus (SCN), functions as a master circadian pacemaker controlling the timing of the sleep-wake cycle and coordinating this with circadian rhythms in other brain areas and other tissues to enhance behavioral adaptation.

Detailed explanation-2: -The SCN is highly sensitive to light, which serves as a critical external cue that influences the signals sent by the SCN to coordinate internal clocks in the body.

Detailed explanation-3: -Sleep is one of the most important physiological functions in mammals. It is regulated by not only homeostatic regulation but also circadian clock. Several neuropeptide-producing neurons located in the hypothalamus are implicated in the regulation of sleep/wakefulness.
