Answer:

The correct answer is B.)Potassium iodide in water

Explanation:

An electrolyte is a compound that can dissociate into ions when is dissolved in a solvent. The resulting solution has the ability to conduct the electricity because there are electrical charges (ions) in the solvent. The most common electrolytes are soluble salts.

From the options, methanol (A), pentane (C) and sucrose (D) are organic compounds that cannot be dissociated into ions in the solvents in which are soluble. The only correct option is (B), because potassium iodide (KI) is a soluble salt that disociates into ions (K⁺ and I⁻) when is dissolved in water:

KI → K⁺ + I⁻
