Correct Answer:
C. Origin
Explanation:
In coordinate geometry, the Cartesian coordinate system relies on two perpendicular lines (the horizontal x-axis and the vertical y-axis) to map dimensions on a plane.
### Important Facts:
- Origin: The unique central intersection point where both axes meet is called the Origin.
- Coordinates: The mathematical coordinates of the origin are defined as $(0, 0)$.
- Quadrants: The intersection of these two axes divides the Cartesian plane into four distinct sections called quadrants.
