A) $\left( x + \frac { 9 } { 2 } \right) ^ { 2 } + \left( y - \frac { 5 } { 2 } \right) ^ { 2 } = \frac { 5 } { 2 }$
B) $\left( x - \frac { 9 } { 2 } \right) ^ { 2 } + \left( y + \frac { 5 } { 2 } \right) ^ { 2 } = 106$
C) $\left\{ x - \frac { 3 } { 2 } \right) ^ { 2 } + \left( y - \frac { 1 } { 2 } \right) ^ { 2 } = 10$
D) $\left( x - \frac { 9 } { 2 } \right) ^ { 2 } + \left( y - \frac { 5 } { 2 } \right) ^ { 2 } = 82$
