Metals are the substances that have more number of electrons. Metals are good conductors of heat and electricity.
For example, iron, copper, zinc are all metals and good conductors of heat and electricity.
Whereas wood and foam are is a poor conductor of heat and electricity.
Thus, we can conclude that out of the given options copper and iron are good conductors of heat.
Answer: Option (B) is the correct answer.
Explanation:
Good conductors are defined as the substance through which heat can effectively pass.
For example, copper, and iron are good conductors of heat and electricity.
Generally, metals are good conductors of heat as well as electricity.
On the other hand, bad conductors are the substances through which heat is unable to flow.
For example, glass, wood, foam etc are all bad conductors of heat as well as electricity.
Thus, we can conclude that out of the given options copper and iron are good conductors of heat.
