Given : $P(x) =x^4 + ax^3 + bx^2 + cx + d$ such that $x=0$ is the real root of $P'(x)=0$. If $P(-1) < P(1)$, then in the interval $[-1, 1]$, which of the following statement is wrong.

Question

$\begin {array} {1 1} \text{(A) P(-1) is the minimum and P(1) is the maximum of P}\\ \text{(B) P(-1) is not minimum but P(1) is the maximum of P} \\ \text{(C) P(-1) is the minimum and P(1) is not the maximum of P} \\ \text{(D) neither P(-1) is the minimum of P nor P(1) is the maximum of P} \end {array}$
