The correct option is
B ꞵ - Galactosidase, Permease, Transacetylase
Lac operon consists of structural genes which are a group of sequences that code for different proteins/ enzymes.
ꞵ - Galactosidase, permease and transacetylase are the various proteins /enzymes produced by the structural genes lac z, lac y and lac a respectively.
The functions of these enzymes are as follows:
ꞵ - Galactosidase → Digests lactose
Permease → Increase permeability of lactose
Transacetylase → plays an important role in lactose utilisation
