Answer:
c. binds to allolactose and becomes inactive, allowing lac gene expression to occur.
Explanation:
Interaction between allolactose and repressor leads to allosteric repulsion which makes repressor inactive leading to the lac gene expression. This is the reason why allolactose is known as the inducer of lac operon becasue it causes gene expression in lac operon.
In the absence of allolactose, the repressor binds the operator and does not allow RNA polymerase to do transcription.
