Cool triple!

If $a$ , $b$ and $c$ are real numbers such that :

$b^2+ac<0$

$c^2+bc<0$ and

$b-a^2>0$ , then which of the following alternatives is true about their numerical sign?.The signs are taken in an order such that the sign of $a$ comes first,the sign of $b$ comes second and finally the sign of $c$ .
