Answer
Liquid carbon tetrachloride
Reason — Liquid carbon tetrachloride (CCl4) is a non-polar covalent compound; it does not ionise in water (and in its pure liquid state contains no ions), so it does not conduct electricity. In contrast, acetic acid is a weak electrolyte (partially ionises), while aqueous solutions of sodium hydroxide and potassium chloride are strong electrolytes because they produce a high concentration of ions in solution.
