Answer:

#"A combustion reaction"#, which sits under the umbrella of #"redox reactions........"#

Explanation:

Typically, an element, metal, sulfur, carbon, is OXIDIZED by oxygen gas to give, for instance a metal or element oxide, and of course, the oxygen is reduced in the reaction.

For carbon we could write:

#stackrel(0)"C"(s) +"O"_2(g)# #""rarr stackrel(+IV)" CO"_2(g)#

Now this is both a #"combustion reaction"#, and a #"redox reaction"#. Oxygen gas is reduced from #stackrel(0)O_2# to #"oxide"#, #O^(2-)# anion.
