How Does RNA Polymerase II Bind to the DNA? ​

How does RNA polymerase II bind to the DNA? ​

A) It binds directly to the eukaryotic promoter sequence.
B) It binds directly to the TATA box.
C) It binds to transcription factors in the nucleus, and the complex then binds to the promoter.
D) Transcription factors first bind to the promoter, then recruit RNA polymerase II.
E) Some transcription factors bind to the promoter while others bind to RNA polymerase II, then the two groups of proteins bind to each other.
