If \int { e ^ { x } - e ^ { - x } }/ { e ^ { 2 x } + e ^ { - 2 x } } d x = \A \log _ { e } | { e ^ { x } + e ^ { - x } + a }/ { e ^ { x } + e ^ { - x } - a } | + c , then ( A , a ) =

Correct Answer is : (12√2,−√2)

( { 1 }/ { 2 \sqrt { 2 } } , \sqrt{ 2 } )

( { 1 } /{ 2 \sqrt { 2 } } , 2 \sqrt { 2 } )

( { 1 } /{ 2 \sqrt{ 2 } } , - 2\sqrt { 2 } )

( { 1 }/ { 2\sqrt { 2 } } , - \sqrt { 2 } )
