The regulation of the mal operon in E. coli that involves the presence of maltose to activate gene expression is an example of **positive control**. In this system, the binding of maltose to a regulatory protein facilitates the initiation of transcription of the genes in the operon. Therefore, the correct response is **positive control**.
