<em>C. Binding to the operator.</em>
Explanation:
When the repressor starts binding to the operator, it can not transcribe, or make mRNA.

The operator functions by making sure the certain DNA gets made, so it is very important. The lac repressor will turn off the expression of the lac genes by binding to the operator.
