    True

    Explanation:

    Input bias current:

    It is a small current that flows in parallel with the input terminals of op-amp to bias the input transistors. This current gets converted into voltage and amplified which results in incorrect output results. This bias current Ib + and Ib - flows in the positive and negative input terminals of the op-amp.

    Ib + and Ib - create errors of opposite polarity. Therefore, bias current can be minimized by carefully adding a resistor in the positive input terminal.

    Input offset current:

    Unfortunately, a small error still remains due to the mismatch between input currents Ib + and Ib-.

    This input offset current error can be adjusted by adding a potentiometer and resistor in the negative input terminal.
