Gene regulation governing lactose operon of E. coli that involves the lac I gene products is:

1. positive and inducible because it can be induced by lactose.
2. negative and inducible because repress or protein prevents transcription.
3. negative and repressible because repress or protein prevents transcription.
4. feedback inhibition because excess of β galactosidase can switch off transcription.
