Option (B) is the correct answer.

Explanation:

It is known that metals are good conductors of heat and electricity. As electricity is the flow of electrons from one point to another and metals are the substances which contain excess of free electrons.

Hence, metals are good conductors of heat and electricity.

For example, gold, silver, copper, aluminium, platinum etc are all metals and good conductors of electricity.

Whereas substances like non-metals are bad conductors of electricity. Substances which do not allow the flow of electric current through it are known as insulators.

For example, plastic, rubber etc are insulators.

Since, Malia's table include silver as bad conductor which is not true.

Thus, we can conclude that Malia's table is incorrect because silver is a good conductor of electricity.
