The correct statement is:
A. The salt has undergone a physical change, and the water has undergone a chemical change.
However, this statement is misleading based on the actual processes that occur during boiling salt water.
In reality, when salt water is boiled, the water undergoes a physical change (evaporation) while the salt remains unchanged and also undergoes no chemical change. Therefore, the best choice based on accuracy would be:
**None of the provided options accurately describe the process.**
A more accurate statement would be: "The water has undergone a physical change (evaporation), and the salt has remained unchanged."
