જો $\alpha, \beta$ એ સમીકરણ $ax^2 + bx + c = 0$ ના બીજ હોય, તો $\lim_{x \rightarrow \beta} \frac{1 - \cos(ax^2 + bx + c)}{(x - \beta)^2}$ ની કિંમત શોધો.

  • A
    $(\alpha - \beta)^2$
  • B
    $\frac{1}{2}(\alpha - \beta)^2$
  • C
    $\frac{a^2}{4}(\alpha - \beta)^2$
  • D
    $\frac{a^2}{2}(\alpha - \beta)^2$
