E Correct answer
Explanation

Initially A has 20L milk, B has 25L water. After transferring 10L milk from A to B: A has 10L milk, B has 10L milk+25L water=35L mixture. When 21L is taken from B (milk:water=10:25=2:5), milk removed = 21×2/7=6L, water = 21×5/7=15L. B left with 4L milk+10L water. Final A: 10+6=16L milk, 15L water. Ratio = 16:15.
