Let the total cost (TC) = C = f(X) for a firm in the short run, which of the following expressions represents the correct relationship between marginal cost (MC) and average cost (AC)? (A) slope of AC = (1/X)/([AC - MC]) (B) slope of AC = 1/X[AC - MC] (C) MC = AC + {X}·{slope of AC} (D) X²·{slope of AC} = X²· MC - C
