Transcription is the transfer of genetic information from DNA to RNA, and it happens in the nucleus.  We can automatically rule out B.  B is incorrect because it doesn't make sense; how can a process stop before it even begins?
A.  I believe this is incorrect because mRNA is involved when the genetic information needs to leave the nucleus.  mRNA would take it to a ribosome outside of a nucleus.  Since transcription happens in the nucleus, mRNA is irrelevant before it starts.
C.  This doesn't really make sense.  mRNA carries information from the DNA, but not vice versa (in these early stages).
D.  This would make the most sense, since RNA polymerase needs to attach to the promoter on the strand before transcription can begin.

Leptin  hormone  is  the  hormones  which  appears  to  be   designed  to  protect  the  body  against  weight  loss.
    Leptin  hormone  is  secreted   from  fat  cells  and  it  helps  to  regulate  body  weight.  Leptin  hormone   is  predominantly made  by  adipose  cell that    help  to  regulate  energy  balance   by inhibiting  hunger. leptin  hormone  is opposed  by  the  action  of  the  ghrelin  hormone which  is  a  hunger  hormone/
