The standard equation of parabola with vertex (h,k) is :

(x - h)² = 4a(y - k)

The given eqation is : (x + 2)² = 4(y - 1)

On comparing the given equation with the standard equation we get

h = -2, a = 1 and k = 1

Vertex is ( h,k)

So, the vertex of the given equation of parabola is (-2, 1)

Answer : B (-2, 1)
