B)Only lacZ would be transcribed.
C)Only lacY would be transcribed.
D)Galactosidase permease would be produced,but would be incapable of transporting lactose.

In the lac operon model proposed by Jacob and Monod, the operator is the binding site for the repressor protein, which prevents RNA polymerase from transcribing the lac genes. If the operator is removed, there would be no repressor binding and the lac operon would be transcribed constitutively, regardless of the presence of lactose. This means that all the genes in the lac operon, including lacZ and lacY, would be transcribed.
