(D) Both (A) and (B)

Adding common salt (sodium chloride) to distilled water creates a solution that can conduct electricity. The dissolved salt dissociates into positive sodium ions (Na+) and negative chloride ions (Cl-), which are free to move in the solution. These mobile ions allow the solution to conduct electricity.

On the other hand, pure distilled water is a poor conductor of electricity because it lacks free ions to carry the electrical charge. It is considered an insulator.

So, when you add common salt to distilled water, it becomes a good conductor of electricity due to the presence of ions, and it is also an insulator without the presence of dissolved ions.
