The focus of a parabola is located at (0,–2). The directrix of the parabola is represented by y = 2.

The vertex lies halfway between the focus at (0, −2) and the directrix y = 2, so the vertex is (0, 0). The parabola has a vertical axis and opens downward; in vertex form, x² = 4py, where p = −2. Thus x² = 4(−2)y = −8y, which is choice D.
