    Let us assume the first part to be = x

    Then

    The second part will be = 2x

    The third part will be = 3 * 2x

    = 6x

    Then we can get to the equation

    x + 2x + 6x = 846

    9x = 846

    x = 846/9

    = 94

    So

    The first part will be = 94

    The second part will be = 2x

    = 2 * 94

    = 188

    The third part will be = 6x

    = 6 * 94

    = 564

    So the three parts are 94, 188 and 564. The second option of 846 = x + 2x + 6x is the correct option.
