The Δ_solutionH is the change in standard molar entropy when a solute is dissolved in a solvent. It depends on the nature of both the solute and the solvent. However, when the solute and the solvent have similar structures or sizes, the change in entropy is likely to be small, and therefore the Δ_solutionH value will be close to zero. Choice D states that two values are close to each other, which indicates similar structures or sizes, so it is the best option.
