Which of the following statements about the effect of the inducer on the repressor-DNA complex is true?

Which of the following statements about the effect of the inducer on the repressor-DNA complex is true?

The inducer waits for the repressor to partially dissociate from DNA and then binds to the newly freed binding site. Upon binding the inducer, a conformational change occurs in the repressor, which loosens the contact between the protein and DNA. The inducer out-competes the repressor for their shared binding site on DNA. The inducer binds to DNA, causing it to partially unwind, thereby loosening the interactions between the repressor and
