The answer is; B
The fluctuation of estrogen in the body is common and its function in a cycle helps regulate the menstrual cycle in females. Therefore, its imbalance is not associated with blood pressure.
Growth hormone affects the renin-angiotensin system that influences blood fluid levels hence affects blood pressure. Norepinephrine is a neurotransmitter that affects dilation and vasoconstriction of blood vessels and the hearts rate hence affects blood pressure. Cortisol is a stress hormone and its increase in the body increases blood pressure. Cortisol is only produced in periods of stress and should not be produced in prolonged periods. Its imbalance, therefore, affects blood pressure.
