B Correct answer
Explanation

Initial mixture: milk = (12/17)×170 = 120L, water = (5/17)×170 = 50L. 20% removed: 34L containing milk = (12/17)×34 = 24L and water = (5/17)×34 = 10L. Remaining: milk = 120-24 = 96L, water = 50-10 = 40L. After adding 10L water: water = 40+10 = 50L. The resultant mixture has 50 liters of water.
