B) Vertex: (0,0) ;Focus: $\left( \frac { 1 } { 10 } , 0 \right)$ ;Directrix: $x = \frac { 1 } { 10 }$
C) Vertex: (0,0) ;Focus: $\left( - \frac { 10 } { 4 } , 0 \right)$ ;Directrix: $x = - \frac { 10 } { 4 }$
D) Vertex: (0,0) ;Focus: $\left( - \frac { 10 } { 4 } , 0 \right)$ ;Directrix: $x = \frac { 10 } { 4 }$
E) Vertex: (0,0) ;Focus: $\left( - \frac { 1 } { 10 } , 0 \right)$ ;Directrix: $x = \frac { 1 } { 10 }$
