B. RNA polymerase transcribes through the terminator sequence, causing the polymerase to fall off the DNA and release the transcript.
Explanation:
Termination of transcription in prokaryotes can be performed in two ways:
Rho dependent-Rho factor is a protein that has the ability to bind for RNA polymerase, and to separate it from the template DNA strand
Rho independent-there is a specific sequence in DNA rich C and G nucleotides. As RNA polymerase gets to that region, it folds the DNA and creates the hairpin. The hairpin causes the polymerase to fall.
