Drawing packages consists of _________.

A Drawing Package (such as AutoCAD, CorelDRAW, Adobe Illustrator, or basic vector graphics tools) is software used to create, manipulate, and render vector-based graphics and technical designs. These packages fundamentally rely on a mathematical approach to construct graphics, which incorporates all the components mentioned in options A, B, and C:

• Co-ordinates: Everything in a digital drawing is plotted on a grid network using mathematical coordinates (like X, Y axes for 2D designs and X, Y, Z axes for 3D designs) to define precise locations.

• Lines: Lines connect different sets of coordinates together. They form the foundational vectors (paths, curves, segments) of any drawing.

• Shapes: Closed paths of lines automatically combine to form complex geometric shapes like rectangles, circles, and polygons.

Since drawing packages fundamentally require a combination of coordinates, lines, and shapes to function, All of these is the correct choice.
