A Correct answer
Explanation

Using alligation: Vessel 1 has milk fraction 8/11 = 16/22, Vessel 2 has 15/22, target is 5/7 = 55/77 ≈ 0.714. The milk fractions are 8/11 ≈ 0.727 and 15/22 ≈ 0.682. By alligation method, the ratio is (55/77 - 15/22):(8/11 - 55/77) = (10/77):(4/77) = 5:2. This matches option A exactly.
