The correct answer is: B. A format for an image file.
A JPG (Joint Photographic Experts Group) file is a type of image file that uses a lossy compression algorithm to reduce the file size. This means that some of the image data is lost when the file is compressed, but the image quality is usually still acceptable. JPG files are often used to store digital photos and other images that need to be stored or transmitted in a small file size.
The other options are incorrect. A Jumper Programmed Graphic is not a real thing. A type of hard disk is not called a JPG. A unit of measure for memory is not called a JPG.
