Electrolyte Concentrations
The measure of the levels of electrolytes, such as sodium, potassium, and chloride, in the body, critical for maintaining proper fluid balance and muscle function.
Extracellular Fluids
Fluids outside of cells, including blood plasma and interstitial fluid, that help transport nutrients, oxygen, and waste products.

Final Answer :
B
Explanation :
The hormone aldosterone is released by the adrenal gland in response to low sodium or high potassium levels in the blood. Aldosterone promotes reabsorption of sodium and excretion of potassium in the kidneys, which helps regulate electrolyte concentrations in extracellular fluids. Cortisol, insulin, and glucagon do not have a direct role in electrolyte regulation.
