The correct answer is C


Explanation

Body water distribution can be calculated using the rule of thirds. 60% of an average persons weight is water. Of this, 2/3 is intracellular and 1/3 is extracellular. Of the extracellular water, 2/3 is interstitial and 1/3 is plasma. In a 50 kg person, there will be 30 kg of water (60%). This will be approximately 30 liters. Of this 1/3 is extracellular or 10 liters.
