Answer:

The reaction between carbon and oxygen to form carbon dioxide can be classified as :

combustion reaction, exothermic reaction and combination reaction.

Hence, the option (C) (I) and (IV) is the correct answer.

It is an exothermic reaction as heat is evolved during the reaction. It is a combination reaction as carbon combines with oxygen to form carbon dioxide. It is a combustion reaction as carbon is burnt in the presence of oxygen.
