Answer:
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.

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period.
