You Are Studying the Affects of Transcription Factors on the Activation

You are studying the affects of transcription factors on the activation of gene expression. However, when first starting your study you notice that some of the transcription factors bind further away from the DNA that it is aiming to transcribe. What description best explains this?

A) The transcription factor transcribes small RNAs that then bind to the promoter and activate the gene's expression.
B) Signals originate via inducers from the transcription factor to the site of promotion that activate transcription of the gene.
C) DNA looping transports the transcription factor closer to the promoter and initiates gene transcription.
D) The assistance of RNA looping moves the transcription factor closer to the promoter.
