Is the Lac Operon Transcribed When Lactose Is Present

Multiple Choice

Is the lac operon transcribed when lactose is present?  

A) Yes, lactose is converted to another sugar that binds to the repressor, freeing the promoter region.
B) Yes, lactose binds to RNA polymerase, allowing it to bind to the promoter and transcribe the operon.
C) No, lactose is converted to another sugar that binds to the two operators preventing transcription.
D) No, lactose has no effect on transcription of the lac operon.
E) No, lactose binds to the second operator, blocking transcription by RNA polymerase.
