Final answer:
Adobe Illustrator is the Adobe program used for creating vector art, known for its ability to scale images without quality loss.
Step-by-step explanation:
If you are creating vector art, the Adobe program you would use is Adobe Illustrator. Vector graphics created with Illustrator can be scaled to any size without losing quality, which is a key feature of vector images. An example of this can be seen in a vector graphics image that was acknowledged to be created with Adobe Illustrator and was verified to have valid SVG source code. Similarly, another example where Inkscape was used for creating vector images shows that there are other software options available for vector art creation; however, Adobe Illustrator remains a professional standard in the industry.
