Correct option is D
The given ratio of milk to water is 3:2. To have more water in the mixture, the water portion should be greater compared to milk.
· 3:4 → More water than the original ratio (since 4 parts water > 2 parts).
· 2:5 → More water compared to milk (5 parts water > 2 parts). Other options do not maintain the same milk-to-water proportion or increase the water content correctly.
