Answer:
A. As mass increases, volume increases
Explanation:
The table in the image attached is depicting the relationship between the mass, volume and density of a certain metal A. Ideally, the density of a substance is directly proportional to its mass, and indirectly proportional to its volume.
However, based on the data provided on this table, the MASS (g) increased as the VOLUME (mL) increased and vice versa. The highest mass of 10.10g has a volume of 3.8mL. This value of volume decreased with decreasing mass. Hence, based on the information of the table, as mass increases, volume increases.
