Solution

The correct option is C
Na₂CO₃

The electrolyte which allows small amounts of electricity to flow through them is called weak electrolyte. These electrolytes are poor conductors of electricity. These electrolytes are partially dissociated in the fused or aqueous solution state. Na $_{2}$ CO $_{3}$ is a weak electrolyte as the solution is partially dissociated in the fused or aqueous solution state.
