Final answer:
The property being compared is surface area.
Step-by-step explanation:
The property being compared in this question is surface area.
When comparing a large salt crystal to smaller table salt crystals, the large salt crystal has a smaller surface area due to its single, larger crystal structure. In contrast, the smaller table salt crystals have a larger surface area because there are more individual crystals, resulting in more exposed surfaces.
So the correct answer is c) Surface area.
