Mate this is wrong, oxidising agents get reduced as they give take electrons from the other molecule. Oxidising is losing electrons so if something is that type of agent, it will make the other molecule lose electrons by accepting the electrons itself.

Correct. An oxidising agent is itself reduced, and vice versa.

Also it's heterogeneous rather than heterogenous but other than that and the comments above a good quiz :)
