What is a primary advantage of using vector images in graphic design?

Using vector images in graphic design offers the primary advantage of guaranteeing high resolution, which is attributed to how vector graphics are created. Vector images are composed of mathematical formulas that define shapes and lines, making them resolution-independent. This means that they can be scaled to any size without losing quality, ensuring that the image remains sharp and clear regardless of how large or small it is printed or displayed. This characteristic is particularly advantageous for designs that may need to be used in various formats, from business cards to billboards, without the risk of pixelation or distortion.

In contrast, the other options present different aspects of image manipulation that do not fundamentally define the unique benefits of vector graphics. While it's true that vector images can be easy to edit, this is not a primary reason to choose vectors over other formats. Additionally, while many vector files are smaller than high-resolution raster images, it is not universally true that they are always small in size. The statement about printing quicker than raster images does not accurately reflect the advantages of vector images either, as print speed generally depends on other factors such as the printer type and settings rather than the image format itself.
