Which of the following is a vector file device?

png
svg
bmp
none of the mentioned

The correct answer is B. SVG.

A vector file is a type of image file that uses lines and curves to represent images, rather than pixels. This makes vector files resolution-independent, meaning that they can be scaled to any size without losing quality. SVG is a vector file format that is commonly used for web graphics. It is an open standard format, which means that it is free to use and there are many different software programs that can create and edit SVG files.

PNG is a raster file format, which means that it uses pixels to represent images. Raster files are not resolution-independent, so they can lose quality when they are scaled. BMP is another raster file format.

D is not a correct answer because it is not a file format.
