In a redox reaction, which of the following statements is true? (2020)

Step 1: Understand what a redox reaction is. A redox reaction involves the transfer of electrons between two substances.
Step 2: Learn the term 'reduction'. Reduction means that a substance gains electrons.
Step 3: Know that when a substance gains electrons, its oxidation state (a measure of how many electrons it has) decreases.
Step 4: Remember that in a redox reaction, one substance is reduced (gains electrons) and another is oxidized (loses electrons).
Step 5: Conclude that the statement 'Reduction is defined as the gain of electrons, which decreases the oxidation state of the element' is true.
