Answer 1

D) The conductivity meter does not light up.

E) Covalent substance; substance that does not conduct electricity.
Explanation: Sugar dissolves but does not form ions, so it’s covalent and the solution is non‑conductive.

F) substance that breaks apart into ions; Ionic substance.
Explanation: Salt (NaCl) dissociates into ions in solution, so it is ionic and the solution conducts electricity.
