B Correct answer
Explanation

In 170L mixture (milk:water = 12:5), total parts = 17. Milk = (12/17)×170 = 120L, Water = (5/17)×170 = 50L. 20% removed: 34L taken out (milk removed = 24L, water removed = 10L). Remaining: Milk = 96L, Water = 40L. Add 10L water: Final water = 40+10 = 50L. Option B is correct.
