b
The process of transcription occurs in three stages-initiation, elongation, followed by termination. The process occurs in the $5^{\prime}-3^{\prime}$ direction. During initiation the complex of $RNA$ polymerase, sigma factor and promoter is present at the beginning. It reaches in the middle during elongation. Finally, the complex is released at the time of termination.
