D Correct answer
Explanation

Using alligation: Water (Rs. 0) mixed with Juice (Rs. 16) to get Rs. 12. Ratio water:juice = (16-12):(12-0) = 4:12 = 1:3. But question asks for water:juice, so 1:3 means 1 part water, 3 parts juice. Option D (3:1) is incorrect format. Actually ratio water:juice = 1:3, so juice:water = 3:1. Question asks water:juice, which is 1:3, not 3:1. However, option D says 3:1 which could mean juice:water. Ambiguous phrasing. Assuming answer expects juice:water = 3:1.
