Answer: Option A

During transcription, the DNA site at which RNA Pol binds is called Promoter.
RNA polymerase and the necessary transcription factors bind to the promoter sequence and initiate transcription. Promoter sequences define the direction of transcription and indicate which DNA strand will be transcribed; this strand is known as the sense strand.
A promoter is a region of DNA where RNA polymerase begins to transcribe a gene. Normally, promoter sequences are typically located directly upstream or at the 5′ ends of the transcription initiation site.
