a. decomposition
b. single replacement
c. double replacement

In a decomposition reaction, a single compound breaks down into two or more simpler substances. Here, compound AB breaks into A and B, which fits the definition of a decomposition reaction. Single - replacement involves one element replacing another in a compound. Double - replacement involves the exchange of ions between two compounds. Synthesis is the opposite of decomposition, where two or more substances combine to form a single compound.

A. Decomposition
