A urine concentration test measures the ability of the kidneys to conserve or excrete water.
A urine specific gravity test compares the density of urine to the density of water. This quick test can help determine how well your kidneys are diluting your urine. Urine that's too concentrated could mean that your kidneys aren't functioning properly or that you aren't drinking enough water.
Urine is concentrated in the final stages of its production: water is absorbed, in excess of solute, from the collecting ducts and into the vasculature of the medulla, thus increasing the osmolality of the collecting duct fluid and thus the osmolality of the urine that emerges from the collecting ducts.

Answer:
The correct answer is a. plasma and interstitial fluid
Explanation:
Extracellular means outside the cell therefore the fluids present outside the cells are called extracellular fluids. Plasma and interstitial fluid are the most abundant extracellular fluid component measuring approx 97% of total extracellular fluid.
Interstitial fluid provide medium for transportation of different substances like nutrients and electrolytes which are important for a cell to function. They are also important for discharge of waste generated by the body cells.
Plasma is yellow colored fluid which contains mostly water and blood cells. They also helps in nutrient transport and waste removal. It makes about 55% of volume of blood.
