Multiple Choice

Find an equation for the surface consisting of all points that are equidistant from the point $( 0 , - 2,0 )$ and the plane $y = 2$ .
Select the correct answer.

A) $x ^ { 2 } + 8 y ^ { 2 } + z ^ { 2 } = 1$
B) $z ^ { 2 } - 8 y ^ { 2 } = x$
C) $z ^ { 2 } + x ^ { 2 } = - 8 y$
D) $z ^ { 2 } - x ^ { 2 } = - 8 y$
E) $x ^ { 2 } + y ^ { 2 } = 8 z$
