Answer:
B. 
Step-by-step explanation:
We have been given a parabola with vertex (h, k) and a vertical axis of symmetry is modeled by the equation
.
We are also given a parabola
.
Let us convert our given parabola equation in axis of symmetry equation as shown below:



Upon comparing our equation with equation
, we can see that
and
.
Therefore, the vertex of the parabola is
and option B is the correct choice.
