Let f(x) be a polynomial of degree 5 such that x = \pm1 are its critical points. If \lim_{x\to0}(2+{f(x)}/x^3)=4, then which one of the following is not true? [7 Jan 2020 Shift 2]

Correct Answer is : x = 1 is a point of minima and x = -1is a point of maxima of f

x = 1 is a point of minima and x = -1is a point of maxima of f

x = 1 is a point of maxima and x = -1is a point of minimum of f
