the amount of water in the blood

Answer:

Option B, The amount of water in the blood

Explanation:

This can be understood from the scenario as described below –

Suppose the quantity of water (volume by volume, v/v or %) in blood is equal to X litre which constitute Y% of the total blood volume.  

Then, the volume of blood can be determined in the following ways-  

Y % of blood volume is equal to X liters

Then  

[tex]\frac{Y}{100}  * Blood Volume [tex]= X\\[/tex] litres

Blood Volume [tex]= \frac{X * 100}{Y} \\[/tex]litres

Thus, in this way if amount of water in blood is known, then the blood volume can be determined.
