Hint: In general, Distilled water is a purified water which do not contain any type of impurities like salts, minerals or any other type of contamination like organic materials, its purified by boiling into vapour and then condensed back into liquid form.
Complete step-by-step solution:
Since, as we know, the chemical formula of common salt is $NaCl$ which is a molecule of sodium atoms and chlorine atoms, now if we add this common salt to purified distilled water.
As distilled water is pure and doesn't contain any form of ions in it which makes it a poor conductor of electricity. When common salt is added to it the sodium and chloride atoms convert into ions form as $N{a^ + }$ and $C{l^ - }$ both ions have a tendency to donate an electron and a tendency to accept the electron.
These free ions $N{a^ + }$ and $C{l^ - }$ are free to move and are available to conduct electricity, so whenever common salt is added to purified distilled water these ions makes distilled water available to conduct electricity and hence makes it good conductor of electricity.
Hence, the correct option is (A) Good conductor.
Note: It should be remembered that, Ions have a positive charge and other one has negative charge so every positive charge cancels each other oppositely charge which makes water neutral but when electricity is passed through them negative charges tends to move in particular direction and hence allows the flow of current easily, which makes water a good conductor of electricity.
