समाकलन $\int {\cos \left( {{{\log }_e}x} \right)dx} $ किसके बराबर है? (जहाँ $C$ एक समाकलन स्थिरांक है)

  • A
    $\frac{x}{2}\left[ {\sin \left( {{{\log }_e}x} \right) - \cos \left( {{{\log }_e}x} \right)} \right] + C$
  • B
    $x\left[ {\cos \left( {{{\log }_e}x} \right) + \sin \left( {{{\log }_e}x} \right)} \right] + C$
  • C
    $\frac{x}{2}\left[ {\cos \left( {{{\log }_e}x} \right) + \sin \left( {{{\log }_e}x} \right)} \right] + C$
  • D
    $x\left[ {\cos \left( {{{\log }_e}x} \right) - \sin \left( {{{\log }_e}x} \right)} \right] + C$
