Given the function f(x), find the functions g(x) and h(x) such that f(x) = g(h(x)) and neither g(x) nor h(x) is solely x. If f(x) = (-4)/(2x-1), which of the following options correctly represents g(x) and h(x)?

A) g(x) = -4 and h(x) = 2x-1
B) g(x) = -4/(2x-1) and h(x) = x
C) g(x) = -4 and h(x) = x
D) g(x) = -4/(2x-1) and h(x) = 2x-1
