Solution

The correct option is B insoluble salts
Double decomposition method is used to prepare insoluble salts. lt involves the reaction between two soluble compounds to produce one soluble and one insoluble products. Amongst the products, the one of importance is the insoluble salt which is gotten as it precipitates out of the solution.
