I think the correct answer is B hope it helped
The correct answer is neuroplasticity.
Neuroplasticity or brain plasticity is the property of the brain to change. Neuroplasticity can be observed at different levels. For example, changes at the cell level can affect connections between neurons (synaptic plasticity), while non-synaptic plasticity refers to changes in the intrinsic part of the neuron. On the other hand, larger-scale changes are usually made by environmental stimuli. Emotions may cause neuroplastic change through activity-dependent plasticity, which is significant for the recovery from brain damage.
Hormones -- such as melatonin and cortisol; the former signals the body to go to bed, while the latter signals for the sleeping person to wake up -- are created by physiological changes.
