b. A mutation in LacI that makes it unable to bind lactose
c. A mutation in LacI that makes it unable to bind glucose
d. A mutation in CRP that makes it unable to bind glucose

A

Explanation:

The lac (lactose) operon is made up of a group of genes that encodes for proteins that are responsible in converting lactose into glucose.The lac operon is found in bacteria such as E.coli , and it is made up of three structural genes:
