a. a teak log that has a large amount of mass for its volume.
b. a copper penny that easily transmits electricity.
c. a diamond that is not easily scratched.
d. a white cotton shirt that reflects all wavelengths of light.

Explanation:

Conductivity is the ability to transmit electricity. A copper penny that easily transmits electricity best represents this physical property. A leaky log with a large amount of mass for its volume is related to density. A diamond that is not easily scratched is about hardness. A white cotton - shirt that reflects all wavelengths of light is about color and light reflection properties.

Answer:

B. A copper penny that easily transmits electricity
