Solution
The correct option is D Lactose
'Lac operon' is a bacterial operon, in which Lactose acts an inducer. The presence of lactose modifies the shape of the repressor (produced by the regulator gene) making it incapable to get attached the on operator. Thus, turning the switch 'on' for transcription and expression of genes.
