જો $\frac{d}{d x}\left(\frac{x \cdot 2^x-x}{1-\cos x}\right)=\left(\frac{x \cdot 2^x-x}{1-\cos x}\right)(f(x)+\log 2)$ હોય, તો $f(x)=$

  • A
    $\frac{1}{x}+\frac{\log 2}{2^x}+\tan \frac{x}{2}$
  • B
    $\frac{1}{x}+\frac{\log 2}{2^x-1}-\frac{\sin x}{1-\cos x}$
  • C
    $x+2^x-1+\sin x(1-\cos x)$
  • D
    $\frac{1}{x}+\frac{\log 2}{2^x-1}+\cot x$
