Which is an example of an exothermic process

Combustion such as lighting a candle , exothermic process is the release of energy in the form of heat

The correct answer is Option C.

Explanation:

Exothermic process is defined as the process in which energy of the products is less than the energy of the reactants. The enthalpy change for these processes comes out to be negative.

Heat is released during these processes. Heat is released when bonds are formed in a chemical reaction.

When a phase change occurs from gaseous to liquid and then to solid state, it results in the release of energy.

Hence, from the given options, only freezing of water is the one where liquid state is getting changed to solid state while releasing heat.

Thus, the correct answer is Option C.
