A good recrystallization solvent should have specific properties that enhance the purification process. The correct answer is based on the fact that volatility at room temperature, while potentially useful to facilitate the removal of the solvent later on, is not a necessary characteristic for a good recrystallization solvent.

The ideal solvent should dissolve the substance of interest well at high temperatures, allowing for effective dispersion during heating, while remaining poorly soluble at lower temperatures to promote crystal formation as the solution cools down. Moreover, a good solvent should dissolve impurities well at low temperatures, ensuring that impurities remain in the solution when the substance crystallizes out. Additionally, the solvent must not chemically react with the substance being recrystallized, which could compromise the integrity of the compound and the outcome of the recrystallization.

Volatility at room temperature is not a critical requirement since effective recrystallization can occur in solvents that do not evaporate quickly. In fact, some less volatile solvents might be preferred for better handling or to avoid the loss of material during the process. Therefore, while the other characteristics contribute directly to the quality of the recrystallization process, volatility at room temperature does not inherently enhance these qualities, making it the correct choice as the property that is NOT typically associated with a good
