The fourth term of the expression (d - 4b)^3 can be determined using the binomial expansion formula. According to the formula, the fourth term is given by:
C(3, 3) * (d)^(3-3) * (-4b)^(3)
= 1 * d^0 * (-64b^3)
= -64b^3
Therefore, the correct answer is -64b^3.
C(3, 3) * (d)^(3-3) * (-4b)^(3)
= 1 * d^0 * (-64b^3)
= -64b^3
Therefore, the correct answer is -64b^3.
