Answer:
a. the coordinated control of gene expression in bacteria
Explanation:
An operon in bacteria is a collection/cluster of genes that are under the control of a single promoter. It includes 3 components: a promoter, the genes and an operator. The operator is where a repressor binds, and the promoter is where transcription begins.
Operons allow organisms to control the expression of multiple genes in response to environmental cues
