A) the presence of glucose would result in a decreased concentration of cAMP in the cell.
B) the lac operon would not undergo an increase in transcription.
C) glucose would be the favoured energy source for the cell.
D) the catabolite-binding protein would bind cAMP to inhibit the expression of the lac operon.
E) RNA polymerase would bind more efficiently to the promoter region of the lac operon.
