Answer: The correct answer is standard reduction potential
Step-by-step explanation:
Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

Standard reduction potential is defined as the tendency of a chemical substance to get reduced. It is denoted as

The substance having highest positive
potential will always get reduced and will undergo reduction reaction.
Hence, the correct answer is standard reduction potential
