B Correct answer
Explanation

In mixture A (ratio 2:5), milk = 2/7 and water = 5/7 of the mixture. In mixture B (ratio 3:4), milk = 3/7 and water = 4/7. When equal quantities are mixed, the final milk proportion = (2/7 + 3/7)/2 = 5/14, and water proportion = (5/7 + 4/7)/2 = 9/14. Therefore, milk:water ratio in mixture C = 5:9.
