What is the reaction called in which a compound breaks down into two or more simpler substances?

Answer and explanation

Correct answer: Decomposition reaction

The governing concept is decomposition: one compound is split into two or more simpler substances. Its general pattern is AB → A + B, and the change may be caused by heat, light, or electricity. Therefore option C is correct. Combination shows the opposite pattern, double displacement exchanges ions between compounds, and combustion is a reaction with oxygen that commonly releases heat and light.
