यदि $f(x) = \frac{1}{\sqrt{x^2 + a^2} + \sqrt{x^2 + b^2}}$ है,तो $f'(x)$ का मान क्या होगा?

  • A
    $\frac{x}{a^2 - b^2} \left[ \frac{1}{\sqrt{x^2 + a^2}} - \frac{1}{\sqrt{x^2 + b^2}} \right]$
  • B
    $\frac{x}{a^2 + b^2} \left[ \frac{1}{\sqrt{x^2 + a^2}} - \frac{2}{\sqrt{x^2 + b^2}} \right]$
  • C
    $\frac{x}{a^2 - b^2} \left[ \frac{1}{\sqrt{x^2 + a^2}} + \frac{1}{\sqrt{x^2 + b^2}} \right]$
  • D
    $(a^2 + b^2) \left[ \frac{1}{\sqrt{x^2 + a^2}} - \frac{2}{\sqrt{x^2 + b^2}} \right]$
