Hello! Your answer would be b, regulation of blood cell size.

The kidneys are vital organs in your body. They filter blood, and extract wastes from it which go on to turn into urine. The kidneys regulate pH, blood osmolarity, blood volume, blood pressure, and ionic composition.

They filter urea, uric acid, excess potassium ions, etc. They also return useful items, such as blood cells, plasma protein, glucose, amino acids, some salts, and some water to the blood. All of these things help contribute to the kidney's job of regulating many aspects of blood.

This is a very brief description of what the kidney does, if you would like a more detailed list, look into secretion, filtration, and reabsorption.

Hope this helps!
