यदि $a > b > 0$ और $x$ न्यूनकोण है,तो $\frac{d}{dx} \left[ \cos^{-1} \left( \frac{b - a \cos x}{a - b \cos x} \right) \right] = $

  • A
    $\frac{\sqrt{a^2 - b^2}}{a - b \cos x}$
  • B
    $\frac{-\sqrt{a^2 - b^2}}{a - b \cos x}$
  • C
    $\frac{\sqrt{a^2 - b^2}}{b \cos x - a}$
  • D
    $\frac{-\sqrt{a^2 - b^2}}{b \cos x - a}$
