Let $a, b \in \mathbb{R}$ $(a \neq 0)$. If the function $f$ is defined as $f(x) = \begin{cases} \frac{2x^2}{a}, & 0 \leq x < 1 \\ a, & 1 \leq x < \sqrt{2} \\ \frac{2b^2-4b}{x}, & \sqrt{2} \leq x < \infty \end{cases}$ 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
    $(-\sqrt{2}, 1+\sqrt{3})$
