D Correct answer
Explanation

Box A has milk:water = 3:1 (milk fraction 3/4). Box B has milk:water = 3:5 (milk fraction 3/8). When mixed, the ratio is 5:3 (milk fraction 5/8). Using alligation method: (5/8 - 3/8) : (3/4 - 5/8) = 2/8 : 1/8 = 2 : 1. So volume ratio A:B is 2:1. Option D is correct. Options A, B, C, E are incorrect.
