    A) It is the recognition site for a specific transcription factor

    Explanation:

    Promoter is non-coding DNA sequence responsible for initiation of transcription, as a first and most import step in the regulation of gene expression. Usually changing of promoter nucleotide sequence can lead to loss of promoter function.

    In eukaryotic cell, promoter is associated with with other regulatory regions such as enhancers, silencers, insulators. The structure of eukaryotic promoter includes the binding site for the enzyme RNA polymerase, site for the binding of regulation factors (such as TATA box), the transcription start site.
