The correct answer is D. It condenses and expands files so they move easily over the Internet.

7-Zip is a file compression and decompression program. It allows you to compress files or folders into a smaller size, making them easier to transfer or send over the internet. It uses various compression algorithms, such as LZMA and LZMA2, to reduce the file size while retaining the essential data. This is especially useful when you need to send large files as email attachments or upload them to a website.

Additionally, 7-Zip can also decompress or extract files from compressed archives. It supports a wide range of archive formats, including its own 7z format, as well as ZIP, RAR, TAR, and more. When you receive a compressed file, you can use 7-Zip to open it and extract the contents.

To use 7-Zip, you simply need to install the program on your computer. Once installed, you can right-click on a file or folder and choose the appropriate options from the context menu to compress or extract files using 7-Zip.
