Which of the following represents the dilute solution?

The correct answer is: 1 gm of sugar in 100 ml of water

As compared to the other options 1 gm of sugar and 100 ml water forms a ratio of 1:100. Rest are forming ratios as 1:5, 1:2, and 5:7 which will not form a dilute solution. A dilute solution is that in which the amount of solute should be more than the amount of solvent. hence 1 gm of sugar and 100 ml water will form a dilute solution.
