ANSWER

EXPLANATION
Since the directrix is 

the axis of symmetry of the parabola is parallel to the y-axis.
Again, the focus being,

also means that the parabola will open upwards.
The equation of parabola with such properties is given by,

where 

is the vertex of the parabola.
The directrix and the axis of symmetry of the parabola will intersect at 

The vertex is the midpoint of the focus and the point of intersection of the axis of the parabola and the directrix.
This implies that,

and 

The equation of the parabola now becomes,


Thus, the distance between the vertex and the directrix.
This means that,

Since the parabola opens up, we choose 

Our equation now becomes,

This simplifies to 

or

This is the same as,

The correct answer is D .
