"The salt crystals dissolve into ions that move freely in water."
Explanation: In solution, ionic compounds break into positive and negative ions. Those charged, mobile ions carry electric current when an electric field is applied. In the solid salt the ions are fixed in the lattice and cannot move, so it does not conduct. The other choices are incorrect because neutral particles do not carry charge and "salt bridges" is a different concept used in electrochemical cells, not the reason a simple salt solution conducts.
