If $f: R \rightarrow R$ and $g: R^{+} \rightarrow R$ are such that $g\{f(x)\}=|\sin x|$ and $f\{g(x)\}=(\sin \sqrt{x})^2$,then a possible choice for $f$ and $g$ is

  • A
    $f(x)=x^2, g(x)=\sin \sqrt{x}$
  • B
    $f(x)=\sin x, g(x)=|x|$
  • C
    $f(x)=\sin ^2 x, g(x)=\sqrt{x}$
  • D
    $f(x)=x^2, g(x)=\sqrt{x}$
