• C. Memory Card
• D. JPEG

Answer: (D)

JPEG is a widely used image file format and compression method designed for photographs. It stands for Joint Photographic Experts Group, the committee that created the standard. JPEG uses lossy compression, meaning it reduces file size by discarding some image data during encoding. You can adjust the quality setting to trade off between file size and image fidelity. Because of its balance of decent quality and small file sizes, JPEG is the default choice for most digital photos and web images, and it’s supported by virtually every camera, phone, app, and browser. It typically stores color information in 24-bit color and does not include transparency. This makes it great for continuous-tone images but not ideal for images with sharp edges or big blocks of flat color where you need crisp edges; for those, formats like PNG might be preferred. The other terms describe things unrelated to a file format—camera viewpoint, editing controls, or a storage card—so they don’t describe what JPEG is.
