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 that the thermostable DNA polymerase used in PCR is isolated from Thermus aquaticus, which directly answers the MCQ about the source of Taq polymerase.
