Detailed explanation-1: -Electrical conductors have free electrons in there outermost shell giving them the property of movement of electrons within the conductor structure and that movement of electrons is also called as current Hence, Electrical conductors provides easy passage to the electrons. Hence A option is correct.
Detailed explanation-2: -Electrons move through a conductor when electric current flows. All materials impede flow of electric current to some extent. This characteristic is called resistance. Resistance increases with an increase of length or decrease of cross-section of a material.
Detailed explanation-3: -Insulators, on the other hand, don’t have free electrons and hence can’t conduct electricity. Q. Good conductors of electricity allow electric current to pass through them.
