Find the general solution of the equation $\sec^{2} 2x = 1 - \tan 2x$.

  • A
    $x = \frac{n\pi}{2}$ or $x = \frac{n\pi}{2} + \frac{3\pi}{8}, n \in \mathbb{Z}$
  • B
    $x = n\pi$ or $x = n\pi + \frac{3\pi}{8}, n \in \mathbb{Z}$
  • C
    $x = \frac{n\pi}{2}$ or $x = n\pi + \frac{3\pi}{8}, n \in \mathbb{Z}$
  • D
    $x = n\pi$ or $x = \frac{n\pi}{2} + \frac{3\pi}{8}, n \in \mathbb{Z}$
