Solution

The correct option is A
Splitting of water into hydrogen and oxygen

Decomposition is a type of chemical reaction in which a single compound splits into two or more simple substances under suitable conditions. Water splitting into two constituent parts is an example of a typical decomposition reaction. All the other remaining examples of, carbon burning in the presence of oxygen, calcium oxide combining with water, oxygen combining with carbon monoxide are all examples of combination reactions.
