Answer:
A
Step-by-step explanation:
Put Y=0
Now
so A is right option
Check the picture below, notice the distance from the focus to the directrix
bear in mind that, the vertex is a distance "p" from the focus point and a distance "p" from the directrix, that simply means, the vertex is half-way between both of those fellows
in this case, the focus point is above the directrix, that means, the parabola is vertical and opens upwards, "p" is a positive number for the focus/point form
so.. check the graph, you know what h,k are, and p, so, plug them in
