Answer:

e. binds to an inducer to activate it.

Explanation:

An active repressor binds to the operator (operon) to either block or start transcription. Some of these proteins are needed routinely, while others are needed only under certain circumstances. For instance, lactose in the lac operon will turn the gene off if the active repressor protein binds to it.
