यदि $\cos A = \frac{7}{25}$ और $\frac{3 \pi}{2} < A < 2 \pi$ है,तो $\cos \frac{A}{4} + \cos \frac{A}{2} - \cos 2A =$

  • A
    $\frac{1}{\sqrt{10}} + \frac{27}{625}$
  • B
    $\frac{3}{\sqrt{10}} - \frac{27}{625}$
  • C
    $\frac{3}{\sqrt{10}} + \frac{27}{625}$
  • D
    $\frac{1}{\sqrt{10}} - \frac{27}{625}$
