The tendency of an electrode to lose or gain electrons when it is in contact with its own ions in solution is called electrode potential.

Since the tendency to lose electrons means also the tendency to get oxidised, this tendency is called oxidation potential. Similarly, the tendency to gain electrons means the tendency to get reduced. Hence this tendency is called reduction potential.

The electrode potential measures the :a)tendency of a cell reaction to...
Electrode potential is defined as the potential difference between the electrode and the solution in which it is dipped. It measures the tendency of the electrode to gain or lose electrons. This potential difference arises due to the exchange of electrons between the electrode and the solution.
Explanation:
• In a galvanic cell or an electrochemical cell, the electrode potential is a measure of the tendency of a cell reaction to occur.
• Electrode potential is the driving force that causes the electrons to flow from the anode to the cathode in a galvanic cell.
• The electrode potential is also used to measure the reactivity of an electrode and its ability to gain or lose electrons.
• The electrode potential depends upon the concentration of ions in the solution, temperature, and pressure.
• The electrode potential is measured in volts and is represented by the symbol E.
• The standard electrode potential is defined as the electrode potential when the concentration of ions in the solution is 1 molar, the temperature is 298 K, and the pressure is 1 atm.
• The standard hydrogen electrode (SHE) is used as a reference electrode to measure the electrode potential of other electrodes. The electrode potential of SHE is considered to be zero.
Conclusion:
Thus, option C is the correct answer as electrode potential measures the tendency of the electrode to gain or lose electrons.
