Answer

Brief Explanations:

Ionic substances dissociate into ions in solution which can conduct electricity and complete the circuit in a conductivity apparatus, causing the light - bulb to light up. Covalent substances do not dissociate into ions in solution and thus do not conduct electricity well, not allowing the circuit to be completed and the bulb to light.

Answer:

C. Ions complete the flow of electrons to form a circuit.
