Condition in which high levels of transcription of structural genes occur in an inducible operon is b)It starts when pathway's substrate is present. So, correct option is b.

In the nonattendance or exceptionally low degrees of glucose as energy source and within the sight of lactose the structural genes of an inducible operon are translated. On the off chance that glucose is available in the medium, there is no need of involving lactose as energy source. Without even a trace of glucose and presence of lactose, lactose ties to the repressor protein and doesn't permit the repressor to tie to administrator and converts it into dormant repressor.

This advances restricting of RNA polymerase to the advertiser of underlying qualities and record happens and mRNA of primary qualities is framed which is meant structure the quality results of z, y and a, as β-galactosidase, permease and transacetylase.

Hence, correct option is b.
