Answer:

The correct answer is Option D i.e. Thermal Decomposition.

Explanation:

Photochemical decomposition is a reaction which is facilitated by sunlight.

Electrolysis is a reaction which occurs in a solution when electricity is passed through it.

In electrolysis, normally salts are decomposed into cations and anions.

Displacement reaction is a reaction in which the entities of two compounds are interchanged.

Thermal decomposition is a reaction which is facilitated in the presence of heat.

The decomposition of zinc carbonate occurs in the presence of heat.

Hence, Option D is correct.
