What is a vector graphic?

A vector graphic is created using paths defined by mathematical expressions, which allows for scalability without losing quality. This means that no matter how much you enlarge or reduce a vector graphic, it maintains sharpness and clarity. Unlike raster images, which are composed of a fixed grid of pixels, vector graphics are resolution-independent. This makes them ideal for logos, illustrations, and designs that require resizing for various applications, such as print and digital media.

The characteristics of vector graphics allow for smooth curves and lines, which can be easily manipulated. They are constructed through points, lines, and curves, all of which are defined mathematically. This foundational structure enables designers to create clean designs that maintain their integrity regardless of the changes in size.

The other choices refer to raster images, which are made up of pixels and are resolution-dependent. Since raster graphics are tied to a fixed resolution, enlarging them often results in a blurry or pixelated appearance. In contrast, vector graphics are prized for their versatility and precision, cementing option B as the accurate description of vector graphics.
