Solution

The correct option is D Iron
Conductors are substances that allow electricity to pass through them freely. The reason is that they contain many atoms that have loosely bound outermost electrons or valence electrons. Metals are good conductors of electricity. However, insulators are just the opposite of the conductors. They do not conduct electricity for example cloth, paper or wood.
