    4⋅ (-9) ⋅ (-3) ⋅ (-1) product is negative,

    Step-by-step explanation:

    Given : Numbers.

    To find : Which product is negative.

    Solution : We have given expression with positive sign and negative sign.

    By the integer rule : When we multiplied the even number of negative it become positive.

    Example: - a * - b = ab.

    When we multiplied the odd number of negative it become negative.

    Example: - a * - b * - c = - abc.

    This expression have - 6⋅ (-7) ⋅ (-8) ⋅0 have 3 negative sign but it has 0 so, this expression would be zero.

    Then only this 4⋅ (-9) ⋅ (-3) ⋅ (-1) expression have 3 negative sign

    So, its product would be negative.

    Therefore, 4⋅ (-9) ⋅ (-3) ⋅ (-1) product is negative,
