Why Does a Solution of Sodium Chloride, NaCl, in Water

Why does a solution of sodium chloride, NaCl, in water conduct electricity?

A) Pure water is a very good conductor of electricity.
B) Solid NaCl is a very good conductor of electricity, so the NaCl particles in the solution conduct electricity.
C) NaCl breaks into the ions Na+ and Cl- that may move through the solution to conduct electricity.
D) The NaCl particle forms a bond with water, thus allowing the solution to conduct electricity.
