B Correct answer
Explanation

Initial mixture has water:milk ratio of 2:7 in 135L, so water = 30L, milk = 105L. Water is doubled to 60L while milk remains 105L. New ratio of water:milk = 60:105 = 4:7. Option A gives an incorrect ratio. Options C, D, and E don't match the simplified ratio after calculation.
