यदि $\int {\frac{{{a^x}{e^{2x}}}}{{{b^x}{c^x}}}dx = \frac{1}{k}\left( {\frac{{{a^x}{e^{2x}}}}{{{b^x}{c^x}}}} \right)} + l$ है,तो $k =$

  • A
    $\log\, b + \log \,c - \log\, a - 2$
  • B
    $\log\, (e^2 \,abc)$
  • C
    $\log\, a - \log\, b - \log\, c + 2$
  • D
    $2\, \log\, a + \log\, b - \log\, c$
