Multiple Choice

If I = $\int$ C $( \sin 2 x - \tan y ) d x + x \sec ^ { 2 } y d y$ is independent of the path where C is a curve from $\left( 0 , \frac { \pi } { 4 } \right)$ to $\left( \frac { \pi } { 4 } , - \frac { \pi } { 4 } \right)$ then I is

A) $\frac { \pi + 2 } { 2 }$
B) $\frac { \pi - 2 } { 2 }$
C) $- \frac { \pi - 2 } { 4 }$
D) $\frac { \pi - 2 } { 4 }$
E) $\frac { \pi + 2 } { 4 }$
