For the Points P and Q, Find the Coordinates of the Midpoint

For the points P and Q, find the coordinates of the midpoint of the segment PQ.
- $\mathrm { P } ( 9 \sqrt { 7 } , \sqrt { 11 } ) , \mathrm { Q } ( - \sqrt { 7 } , 4 \sqrt { 11 } )$

A) $\left( 5 \sqrt { 7 } , \frac { \sqrt { 11 } } { 2 } \right)$
B) $\left( 4 \sqrt { 14 } , - \frac { \sqrt { 33 } } { 2 } \right)$
C) $\left( 4 \sqrt { 7 } , \frac { 5 \sqrt { 11 } } { 2 } \right)$
D) $( 4 \sqrt { 7 } , 5 \sqrt { 11 } )$
