Carbon monoxide.

Reason: CO is a good reducing agent (reduces metal oxides in metallurgy) and is also a combustible fuel (oxidises to CO2). Heavy metal oxides are generally oxidizing, concentrated H2SO4 is an oxidizing/dehydrating agent, and H2O2 is mainly an oxidizer (though it can act as a reductant in special cases, it is not typically a fuel).
