Answered by GPT-5 mini AI
Potassium chloride.

Reason: KCl is an ionic salt that dissolves in water and fully dissociates into K+ and Cl− ions, providing many charge carriers so its aqueous solution is an excellent electrical conductor. Methanol is a non‑electrolyte, acetic acid is a weak electrolyte (poor conductor), and distilled water has very low ion content and poor conductivity.
