Multiple choice

if $\alpha$ and $\beta$ are the roots of the equation $ax^ {2}+bx+c=0$ then the sum of the roots of the equation $a^ {2}x^ {2}+\left(b^ {2}-2ac\right)x+b^ {2}-4ac=0$ is

$-\left(\alpha^ {2}-\beta^ {2}\right)$
$\left(\alpha+\beta\right)^ {2}-2\alpha\beta$
$\alpha^ {2}\beta+\beta\alpha^ {2}-4\alpha\beta$
$-\left(\alpha^ {2}+\beta^ {2}\right)$
