Correct answer is a molecule that functions as the electron donor in a redox reaction loses electrons and becomes oxidised.
Oxidation reduction reactions involve transfer of electrons between species.
One species is the electron donor that will lose its electrons and other is an electron acceptor that will accept those electrons.
Electron donor once it loses its electrons becomes oxidised. Electron acceptor once it gains the electrons becomes reduced.
Therefore electron donor loses its electrons and becomes oxidised.
