Solution
The correct option is C Electrons
Indirect redox reactions only take place if in between the electrodes is an environment that is conducive for electric current (meaning that charged particles are present that can freely move around, like the ions of dissolved or molten salts). There is no direct contact between the particles of the oxidation and the reduction. The transfer of the electrons is realised via-via, mostly via metal wiring or other conductive material.
Exteriorly the conducting wires take care for the electron transport from RED to OX, without direct contact between the reactants.
