Which of the following is the least likely mechanism for reducing the rate of gene transcription by a repressor?

C. The binding of the repressor sterically occludes binding of the RNA polymerase to the promoter.
D. The repressor binds directly to the DNA to stabilize the closed complex over the open complex.
