Fight-or-flight reactions cause activation of

Options

A. the parathyroid gland, leading to increased metabolic rate
B. the kidney, leading to suppression of reninangiotensin-aldosterone pathway
C. the adrenal medulla, leading to increased secretion of epinephrine and norepinephrine
D. the pancreas leading to a reduction in the blood sugar levels
