In E. Coli, under high lactose, high glucose conditions, which of the following could lead to maximal transcription activation of the lac operon?

(A) A mutation in the lac I gene (which encodes the repressor)

(B) A mutation in the CRP binding site leading to enhanced binding

(C) A mutation in the operator sequence

(D) A mutation leading to enhanced cAMP levels

(E) A mutation leading to lower binding of repressor
