Answer: Option (b) is the correct answer.
Step-by-step explanation:
A solution that contains more amount of a solvent and less amount of a solute is known as a dilute solution. This means that concentration of a solute is less in a dilute solution.
For example, when 5g of NaCl is dissolved in 1 liter of water then it will be a dilute solution.
On the other hand, a solution that contains more concentration of a solute in a solvent is known as a concentrated solution.
For example, 800 g of NaCl is 1 liter of water will be a concentrated solution.
Therefore, we can conclude that when comparing two solutions with the same volume, you may say that one is dilute and the other is concentrated this means that the dilute solution contains less solute than the concentrated solution.
