Correct Answer:
C. .zip
File compression is the process of reducing the size of one or more files to save disk space or facilitate faster transmission. Option C, ".zip," is the most common and widely recognized file extension for compressed archives. The .zip format allows multiple files and folders to be bundled into a single file, significantly reducing their overall size.
Option A (".docs") is incorrect; .docs is typically associated with Microsoft Word document files.
Option B (".cmp") is not a standard or widely used file extension for general file compression.
Option D (".clp") is often associated with Windows Clipboard files, which store clipboard contents, not compressed files.
