Which format is best described as vector graphics, defined by lines and curves and scalable without quality loss?

Explanation:
Think about how the image is stored. If it’s described using lines and curves defined by mathematical rules, it stays crisp no matter how much you scale it. That’s exactly what defines vector graphics: lines and curves that can be resized without losing quality. In contrast, JPEG and PNG are raster formats made from pixels, so scaling up typically reveals blur or blocky pixels because the image must be resampled, not redrawn. So this description points to vector graphics as the best fit, the type you’d use for logos or illustrations that need to stay sharp at any size.
