An equation is shown below:

-2(4x - 1) - 7 = 5

Which statement shows a correct next step in solving the equation?
(A) The equation can become -2(4x - 1) = -2 by applying the distributive property.
(B) The equation can become -2(4x - 1) = 12 by applying the addition property of equality.
(C) The equation can become -2(4x - 1) = 12 by applying the commutative property of addition
(D) The equation can become -2(4x - 1) = -2 by applying the subtraction property of equality.
