The correct answer is D because in rho-independent termination of RNA transcription in E. coli, the RNA transcript indeed contains self-complementary sequences that can form a hairpin structure, and there are also three conserved adenine (A) residues in the template strand near the end of the transcript, which facilitate the termination process by weakening the RNA-DNA hybrid in the transcription bubble, making it easier for the newly synthesized RNA to dissociate from the DNA template.
