यदि $\int \frac{\cos \theta}{5+7 \sin \theta-2 \cos ^2 \theta} d \theta=A \log _e|f(\theta)|+c$ (जहाँ $c$ समाकलन का एक स्थिरांक है),तो $\frac{f(\theta)}{A}$ क्या हो सकता है?

  • A
    $\frac{2 \sin \theta+1}{\sin \theta+3}$
  • B
    $\frac{2 \sin \theta+1}{5(\sin \theta+3)}$
  • C
    $\frac{5(\sin \theta+3)}{2 \sin \theta+1}$
  • D
    $\frac{5(2 \sin \theta+1)}{\sin \theta+3}$
