What role does the oxidizing agent play in a redox reaction? a. the oxidizing agent receives electrons from the reducing agent. b. the oxidizing agent loses electrons to the reducing agent. c. the oxidizing agent reduces the reducing agent. d. the oxidizing agent increases the reducing agent.

Answer is "the oxidizing agent receives electrons from the reducing agent".

There are two types of reactants in redox reactions. One is oxidizing agent and other is reducing agent.

Oxidizing agent is a substance which helps to oxidize other substance by gaining electrons. This is also called as oxidizer. Due to the gaining electrons, oxidizing agents tend to be reduced.

Reducing agent or reducer helps to reduce other substance while loosening electrons. Hence, reducing agents tend to be oxidized.
