B) The water molecules remain together. The salt molecules break apart.
Step-by-step explanation:
When the salt is being place upon the water, the sodium in salt becomes attracted to the water molecules. Both H20(water) & NaCI (salt) start to become drawn, during this reaction. This causes water to remain together, while the salt is broken apart and dissolves. Hope this helps!
