Solution

The correct option is A Electron
A Redox reaction involves reduction and oxidation processes in which gain of electron and removal or loss of electrons in reduction and oxidation takes place respectively. Majority of the energy reactions in living systems are oxidation-reduction reactions.
So, the correct option is 'Electron'.

Q. Which one is always transferred in redox reaction?

Q. Assertion :Oxidation involves loss of electrons and reduction involves gain of electrons. Reason: The overall reaction in which oxidation and reduction occurs simultaneously is called redox reaction.

Q. Assertion :Galvanic cell convert chemical energy into electrical energy. Reason: Redox reactions are those in which oxidation takes place at anode and reduction at cathode.
