D Correct answer
Explanation

Statement I: Initial water is 2/11 of total (44 liters). So water = 8 liters, milk = 36 liters. After adding x liters water, water becomes 1/3 of total. (8+x)/(44+x) = 1/3, solving gives x = 10. Then milk:water ratio = 36:18 = 2:1. Statement I alone is sufficient. Statement II: Finally milk is 3/4 of total, so water is 1/4. Water was 8, becomes (8+x)/(44+x) = 1/4. Solving gives x = 10, ratio = 2:1. Statement II alone is also sufficient.
