B Correct answer
Explanation

The milkman buys 18 liters at Rs 10/liter (Total cost = 180). He sells 18 liters, but uses a 900ml measure for every liter, effectively selling 18 * (1000/900) = 20 liters worth of milk at Rs 12/liter. Total revenue = 20 * 12 = 240. Profit = 240 - 180 = 60. Profit percentage = (60/180) * 100 = 33.33%.
