Answer: Option C

Explanation:

In computer graphics, graphics software refers to a program or collection of programs that enable a person to manipulate images or models visually on a computer.

Computer graphics can be classified into distinct categories: raster graphics and vector graphics, with further 2D and 3D variants. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that operate on both.

It is simple to convert from vector graphics to raster graphics, but going the other way is harder. Some software attempts to do this.
