## Answer

The correct option is **C: $AB \rightarrow A + B$**

In a **decomposition reaction**, a single compound breaks down into two or more simpler substances. For instance, **silver chloride** ($ \mathrm{AgCl} $) decomposes into **silver** ($ \mathrm{Ag} $) and **chlorine** ($ \mathrm{Cl}_2 $) when exposed to sunlight. The reaction can be represented as:
$$
2 \mathrm{AgCl}(\mathrm{s}) \xrightarrow{\text {Sunlight}} 2 \mathrm{Ag}(\mathrm{s}) + \mathrm{Cl}_2(\mathrm{g})
$$

Therefore, the general representation of a decomposition reaction is: $$ AB \rightarrow A + B $$
