The correct answer is B) Conductor
A conductor is a material that allows for the flow of electrical charge (electrical current). This type of material provides little or no resistance to the flow of electric current. This is due to the fact that these type of materials have free electrons which conduct the flow of electrical current in any direction.
Different types of conductors have different resistances. Some types of materials are good conductors whereas some are not so good.
Some common conductors are Copper, gold, silver and aluminium.
An insulator is the an object of type of material which have a strong resistance to the flow of electric current. Some common insulators are glass, wood and plastic.
