    B.

    Explanation:

    For a given set of input values, A NAND gate produces exactly the same values as an OR gate with inverted inputs.

    The truth table for a NAND gate with 2 inputs is as follows:

    0 0 1

    0 1 1

    1 0 1

    1 1 0

    The truth table for an OR gate, is as follows:

    0 0 0

    0 1 1

    1 0 1

    1 1 1

    If we add two extra columns for inverted inputs, the truth table will be this one:

    0 0 1 1 1

    0 1 1 0 1

    1 0 0 1 1

    1 1 0 0 0

    which is the same as for the NAND gate, not the opposite, so the statement is false.

    This means that the right choice is B.
