    In electric circuit, the potential difference is always developed across the resistance.

    Now is we are to amplify the voltage, that means low input voltage is converted into high voltage output.

    Therefore we require low resistance at input for low voltage and high out put resistance for high output

    Thus the statement given is wrong.
