Which of the solutions shown below taken as an electrolyte shows a deflection in the compass needle when connected in a circuit?

Vinegar is taken as an electrolyte and shows a deflection in the compass needle when connected to a circuit.
Vinegar shows a deflection in the compass needle when taken as an electrolytic solution. Vinegar is also called acetic acid. Acids taken as an electrolyte will always conduct electricity through them. This is because acids have free ions present in them in their solution. Free ions are required to conduct electricity through a solution. As other options do not contain ions in their solution, they do not conduct electricity.
