જો $\int {{e^{\sec x}}\left( {\sec x + \tan x f(x) + (\sec x \tan x + \sec^2 x)} \right)dx = {e^{\sec x}}f(x) + C}$ હોય,તો $f(x)$ ની શક્ય પસંદગી કઈ છે?

  • A
    $\sec x - \tan x - \frac{1}{2}$
  • B
    $x \sec x + \tan x + \frac{1}{2}$
  • C
    $\sec x + x \tan x - \frac{1}{2}$
  • D
    $\sec x + \tan x + \frac{1}{2}$
