Let $a, b \in R, (a \ne 0)$. If the function $f$ defined as
$f(x) = \begin{cases} \frac{2x^2}{a}, & 0 \le x < 1 \\ a, & 1 \le x < \sqrt{2} \\ \frac{2b^2 - 4b}{x^3}, & \sqrt{2} \le x < \infty \end{cases}$
is continuous in the interval $[0, \infty)$,then an ordered pair $(a, b)$ is

  • A
    $(- \sqrt{2}, 1 - \sqrt{3})$
  • B
    $(\sqrt{2}, -1 + \sqrt{3})$
  • C
    $(\sqrt{2}, 1 - \sqrt{3})$
  • D
    $(- \sqrt{2}, 1 + \sqrt{3})$
