જો $f(x)$ એ સતત અને વિકલનીય વિધેય હોય જે $f(x) \cdot f(f(x)) = x^2 + 1$,$f(1) = 2$,અને $f'(1) = k$ નું પાલન કરે છે,તો $f'(2)$ ની કિંમત શું થાય?

  • A
    $\frac{1}{k} - \frac{1}{2}$
  • B
    $\frac{1}{k+1} - \frac{1}{2}$
  • C
    $\frac{1}{k+2} - \frac{1}{2}$
  • D
    $\frac{1}{k+3} - \frac{1}{2}$
