Inducible genes are the genes which remain inactive or repressed in a cell and can be activated when a certain substrate is to be metabolised. It has been seen when lactose is added to the medium of E.coli the operon is induced and synthesis of enzymes required for degradation of lactose to glucose and galactose starts.Hence, the correct answer is option 3.
