જો $f(x) = \sqrt{\log(x^2+x+1) + \sqrt{\cosh(2x-3)}}$ હોય, તો $f'(0) =$

  • A
    $\frac{1}{2 \sqrt{\sqrt{\cosh(3)}}} \left(1 + \frac{\sinh(3)}{\sqrt{\cosh(3)}}\right)$
  • B
    $\frac{1}{2 \sqrt{\sqrt{\cosh(3)}}} \left(\log 3 - \frac{\sinh(3)}{\sqrt{\cosh(3)}}\right)$
  • C
    $\frac{\log 3 \sqrt{\cosh(3)} - \sinh(3)}{2(\cosh(3))^{3/4}}$
  • D
    $\frac{\sqrt{\cosh(3)} - \sinh(3)}{2(\cosh(3))^{3/4}}$
