What defines a vector graphic?

A vector graphic is defined by its ability to store properties of each shape in the image, which allows for scalable and resolution-independent illustrations. Unlike raster images, which are made up of a grid of pixels (the first choice), vector graphics use mathematical equations to represent shapes such as lines, curves, and polygons. This means that they can be resized without loss of quality, making them ideal for logos, illustrations, and other types of graphics where clarity at any size is important.

The other options do not accurately describe vector graphics. While a program that modifies file attributes may be related to how vector graphics files are handled, it does not define what a vector graphic actually is. Similarly, a type of memory storage is a broader concept that does not pertain specifically to the characteristics that make up vector graphics. Thus, the definition that highlights the storage of properties of each shape aligns with the fundamental nature of how vector graphics are created and manipulated.
