Which one of the following reactions is expected to readily give a hydrocarbon product in good yields?

Step-by-step solution

Electrolysis of a concentrated aqueous solution of either sodium or potassium salts of saturated carboxylic acids yields higher alkane at anode. 2 RCOOK Oxidation Electrolytic Anode 2 RCOO ⁻ + Cathod 2 ~K ⁺ At anode 2 RCOO ⁻ 2 RCOO +2 e ⁻ R - R +2 CO ₂ At Cathode 2 ~K ⁺+2 e ⁻ 2 ~K 2 ~K + H ₂ O 2 KOH + H ₂ (Kolbe's Method)
