Here, we have to find the equation of the parabola whose focus is at F(0, - 3) and directrix y = 3. As we know that, parabola of the form x2=−4ay has focus at (0, - a) and equation of directrix is given by y = a. So, by comparing the focus F(0, - 3) and directrix y = 3 with (0, - a) and y = a respectively we get ⇒a=3 So, the equation of the required parabola is x2=−4⋅3⋅y=−12y Hence, option C is the correct answer.
