Final answer:
Metal from the provided options is a thermal conductor, as it allows for efficient transfer of thermal energy, while plastic, wood, and rubber are considered insulators.
Step-by-step explanation:
Based on the data provided, metals can be classified as thermal conductors because they conduct thermal energy faster than other materials like wood, plastic, and rubber. For example, copper and aluminum are metals with good thermal conductivity, making them capable of conducting heat efficiently. In contrast, materials such as plastic, wood, and rubber are poor heat conductors as they are typically insulators of electricity and do not allow thermal energy to move through them easily.
Therefore, the material from the list that can be classified as a thermal conductor is c) Metal. The other materials listed - plastic, wood, and rubber, are generally considered insulators rather than conductors of thermal energy.
