JEE Math Practice Question

If $$\alpha$$, $$\beta$$ are the distinct roots of x2 + bx + c = 0, then $$\mathop {\lim }\limits_{x \to \beta } {{{e^{2({x^2} + bx + c)}} - 1 - 2({x^2} + bx + c)} \over {{{(x - \beta )}^2}}}$$ is equal to :

1. A.b2 + 4c
2. B.2(b2 + 4c)
3. C.2(b2 $$-$$ 4c)
4. D.b2 $$-$$ 4c
