Answer:
Substance C
Explanation:
From the statement scenario, it is given that no water remained above substance C. This then means that substance C actually absorbed all the water above it faster than the two other substances.
Therefore, we can deduce that substance C has the greatest porosity. This means that it has the highest amount of spaces within where the water can be absorbed.
Porosity has to do with the available empty spaces which is within a material. This property allows materials or substances to absorb other substances that are absorbable.
