The answer is 1) electrical energy spontaneously
A voltaic cell is an electrochemical cell driven by a spontaneous chemical reaction and produces an electrical energy. The general form of reaction is reagents → products + electrical energy. This reaction is spontaneous.
However, the reverse reaction is nonspontaneous and it requires electrical energy.
A voltaic cell produces electrical energy spontaneously by converting the energy released from a spontaneous chemical reaction. This fundamental process involves the transfer of electrons from the anode to the cathode, creating an electric current. The chosen answer is option 1) electrical energy spontaneously.
