A) Center: (0, 0) Vertices: (0, 0) Foci: $( \sqrt { 21 } , 0 )$
B) Center: (0, 0) Vertices: $( 0 , \pm \sqrt { 5 } )$ Foci: $( \pm \sqrt { 26 } , 0 )$
C) Center: (0, 0) Vertices: $( \pm \sqrt { 5 } , 0 )$ Foci: $( \pm \sqrt { 26 } , 0 )$
D) Center: (0, 0) Vertices: $( - \sqrt { 5 } , 0 )$ Foci: $( \pm \sqrt { 26 } , 0 )$
E) Center: (0, 0) Vertices: $( 0 , \pm \sqrt { 5 } )$ Foci: $( 0 , \pm \sqrt { 26 } )$
