Solution

The correct option is C 4 days
To purify the blood and to remove toxins the human has to purify the blood before the whole blood gets converted into waste. The rate of conversion is 1 litre per day and total blood is 5 litres, this means that the body will take 5 days to convert the whole blood into waste. Hence, he will need to undergo dialysis every 4 days.
