Which of the following is a common file format for images?

• A. PDF
• B. JPEG
• C. HTML
• D. EXE

Answer: (B)

JPEG is a widely used file format specifically for compressing images. It is particularly popular for photographs and complex images due to its ability to reduce file size while maintaining a reasonable level of visual quality. JPEG files use a lossy compression method, which means that some image quality is sacrificed to achieve smaller file sizes, making it suitable for web use and storage.

In contrast, the other options serve different purposes: PDF is primarily used for documents and presentations that combine text and images; HTML is a markup language used for creating web pages; and EXE files are executable files used to run programs on a computer. Each of these formats is not designed primarily for storing or compressing digital images, making JPEG the most appropriate choice for this question.
