Answer:
B. 8 units
Step-by-step explanation:
We have been given that the distance between the given point and the parabola's focus is 8 units. We are asked to find the distance between the given point on a parabola and the parabola's directrix.
By definition a parabola is set of all points in a plane which are an equal distance away from a given point (focus) and given line (directrix).
Since our given point is 8 units away from focus, so the point will be 8 units away from directrix, therefore, option B is the correct choice.
