Solution

The correct option is C
Chemical and combination reaction

Formation of water is a chemical reaction because in this reaction a new compound is formed. It is also a combination reaction because hydrogen and oxygen combine to form a single product (water). The reaction is $2 H_{2} (g) + O_{2} (g) \to 2 H_{2} O (l)$ .
