Hint: An electric plug is used for the connection of electrical equipment to the supply of electric current. As there is direct contact of people to the body of the electric plug, the material used should have the maximum resistivity or zero conductivity to avoid any danger to human life.
Complete step by step answer:
We know plugs are used to connect any electrical equipment to the main electric current supply. As we all know people will have direct contact with the body of the plug when we connect any electrical equipment to a main supply. If there exists any direct contact with the electric flow, it will be very dangerous and harmful to the people.
So any chance of direct contact of people with the electric current flow should be avoided. For that insulators are used. Insulators are made of materials which have zero conductivity of electricity. Plastic is one of the best examples of insulators. That is plastic can be used as an insulator or any other component which is used to avoid direct contact of people to the electric current flow.
This is the reason why plastic are used for the making of electric plugs
The final answer is option (C), Plastic protects people from electricity.
Note: Insulators used for high-voltage power transmission are made from glass, porcelain or composite polymer materials. Porcelain is the material that is most commonly used for overhead insulators recently. The porcelain is made of aluminum silicate. The aluminum silicate is mixed with feldspar, plastic kaolin and quartz to obtain final hard and glazed porcelain insulator material.
