(B) The $lac$ operon is a classic example of an inducible operon system.In the absence of the inducer (lactose),the repressor protein binds to the operator region of the operon.This binding physically prevents the $RNA$ polymerase from transcribing the structural genes.Since the binding of the repressor protein inhibits the expression of the operon,this type of control is referred to as negative regulation.

The regulation of the $lac$ operon by a repressor is known as:
