Tangents are drawn from the point $P ( 3,4 )$ to the ellipse $\frac { x ^ { 2 } } { 9 } + \frac { y ^ { 2 } } { 4 } = 1$ touching the ellipse at points A and B.
The orthocenter of the triangle $P A B$ is\\
A) $\left( 5 , \frac { 8 } { 7 } \right)$\\
B) $\left( \frac { 7 } { 5 } , \frac { 25 } { 8 } \right)$\\
C) $\left( \frac { 11 } { 5 } , \frac { 8 } { 5 } \right)$\\
D) $\left( \frac { 8 } { 25 } , \frac { 7 } { 5 } \right)$
