The correct answer is: a. A site in DNA that recruits the RNA Polymerase
Promoters are regions of DNA molecule located near the transcription start codons of genes, usually upstream on the DNA with the function to initiate DNA transcription. Promoters contain specific DNA sequences (e.g. TATA boxes) that are binding sites for the enzyme RNA polymerase and transcription factors that recruit RNA polymerase. Transcription factors can regulate gene expression and act as activators or repressors depending on sequences that attach to specific promoters.
