Show answer & explanation
Correct answer: B
Correct answer: Points and Lines.
Explanation: Points represent discrete locations (vertices). Lines connect two points to form edges. These two primitives are the fundamental elements used to construct more complex graphics.
Polylines are sequences of connected line segments and therefore are composed from lines (and points).
Polygons are closed polylines (often filled) and are built from lines and points.
Conclusion: Points and lines are the basic building blocks; polylines and polygons are higher-level constructs derived from those primitives.
