A teacher gives Martina two objects. The teacher also gives Martina a chart that describes four properties of some materials as shown. The teacher tells Martina that one object is made from copper and the other object is made from iron. Based on the information in the chart, which observations will help Martina identify which object is made from copper?

A.

B.
The object would not conduct electricit, and it would be black.

C.
The object would not be attracted to a magnet, and it would be orange.

This observation would help Martina identify that the object made from copper is the one that is not attracted to a magnet and is orange, as copper is not magnetic and has a characteristic orange color.
