Answer is Termination
Explanation: Complete RNA transcript has synthesized. This means Transcription is over. and arrow indicates removal of RNA polymerase from the RNA-DNA duplex. Therefore it is termination.
Answer can't be initiation as complete RNA transcript has synthesized and removal of RNA polymerase has been shown by an arrow. This cant be elongation as RNA polymerase is removed from RNA-DNA duplex. There is no phase in the transcription so called Disengagement.

RNA polymerase releases the DNA template. Initiation Elongation Termination A process called clearance or escape. The RNA polymerase holoenzyme binds to the promoter A process called clearance or escape. Reaching a terminator sequence causos formation of phosphodiester bonds to stop. The RNA polymerase holoenzyme is formed. Once bound to the promoter, RNA polymerase begins to unwind the DNA. New nucleotides are added to the 3' end of the growing RNA transcript. The RNA-DNA hybrid within the transcription bubble dissociates New...
