GPT-4o mini · Answer

The correct statement is: **Substance B has stronger bonds, and it takes more energy to undergo a phase change.** Explanation: Boiling points are indicative of the strength of intermolecular forces. A higher boiling point generally means that the substance has stronger intermolecular forces (in this case, hydrogen bonding in both substances). Therefore, since Substance B has a boiling point of 100ºC compared to Substance A's 78.4ºC, it suggests that Substance B has stronger hydrogen bonds and requires more energy to overcome these forces during a phase change (such as boiling).
