Explanation:

Elements are grouped into metals, nonmetals, and metalloids based on shared characteristics (e.g., conductivity, luster, malleability). Color, row position, and mass do not define these categories. Similar properties are the key classification criterion.

Answer:

C. The elements in each group have similar properties.
