Which file extensions are commonly used to transfer image data over FTP?

The correct choice includes file extensions that are specifically associated with image formats used for transferring visual data. BMP (Bitmap), GIF (Graphics Interchange Format), and JPG or JPEG (Joint Photographic Experts Group) are all standard image file types widely utilized for various purposes, including website images, photographs, and graphics. These formats are natively designed to store image data and are optimized for use in many applications that require visual content.

This is significant because when transferring image data over FTP (File Transfer Protocol), the primary focus is on formats that maintain image quality and compatibility with different software and devices. These file types are recognized for their ability to efficiently handle visual information while maintaining the integrity of the image during transfer.

The other options consist of file types that either pertain to different kinds of data or are compressed formats. The first choice lists office document formats that are not relevant to image data, while the second includes text and layout formats. The last option relates to compressed file formats, which may sometimes contain images, but they do not represent image formats themselves. Therefore, the presence of BMP, GIF, and JPG or JPEG clearly identifies choice C as the most appropriate answer for image transfers over FTP.
