Solution
The object that is defined using a directrix and a focus is a Parabola (C).
Here's a step-by-step explanation:
-
A parabola is a set of all points in a plane that are equidistant from a given fixed point and a given fixed line.
-
The fixed point is called the focus of the parabola and the fixed line is called the directrix.
-
The property that defines a parabola is that, for any point on the parabola, the distance to the focus equals the distance to the directrix.
-
Therefore, a parabola is the object that is defined using a directrix and a focus.
