`a, b in RR` be such that the function f given by `f(x)=ln|x|+bx^(2)+ax,xne0` has extreme values at `x=-1` and x = 2.
Statement-I : f has local maximum at x = -1 and at x = 2.
Statement-II : `a=(1)/(2)" and "b=-(1)/(4)`.

A

Statement-I is true, Statement-II is true, Statement-II is not a correct explanation for statement-I.

B

Statement-I is true, Statement-II is false.

C

Statement-I is false, Statement-II is true.

D

Statement-I is true, Statement-II is true, Statement-II is a correct explanation for Statement-I.
