    Numbers 4, 6, & 7 are correct

    Explanation:

    4 - this allows the op amp to have zero voltage so that maximum voltage is transferred to output load.

    6 - this ensures that op amp doesn't cause loading in the original circuit, high input impedance would not deter the circuit from pulling current from it.

    7 - high difference between upper and lower frequencies.
