    C

    Explanation:

    In regression, the critical value t for testing the significance of variable's coefficients has the number of degrees of freedom formula which is (number of observations) - (number of independent variables + 1).

    Where number of observations = 697

    number of independent variables = 17

    Hence, in this case we have

    697 - (17+1) = 697 - 18 = 679 degrees of freedom.
