The NCERT line that answers it

Verbatim line

The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly states 'A Rho factor (ρ) binds to the RNA polymerase, causing it to dissociate from the DNA template and release the synthesized RNA strand,' which directly matches the fact in option B that RNA polymerase binds with Rho factor to terminate transcription in bacteria.
