"The process of dissolving frees the atoms in the solution to move." — option 2.
When salt (an ionic compound) dissolves it dissociates into mobile charged ions (e.g., Na+ and Cl–). These ions can move and carry electric charge through the solution, so the solution conducts electricity. Pure solid salt has ions locked in a lattice and pure water has very few ions, so both are poor conductors.
