The correct answer is:
The polymerase would denature due to the high temperatures of PCR, and no copies would be produced.
Human DNA polymerases, such as DNA polymerase I or II, are not heat-stable and would denature and lose their functionality at the high temperatures used during PCR (typically around 95°C for denaturation). This is why thermostable DNA polymerases like Taq polymerase are used in PCR, as they can withstand the high temperatures without denaturing.
