what does a file extension tell your computer?
when the file was created
where a program is saved
what type of program to open
which file name to display

Explanation:

A file extension (e.g., .docx, .jpg, .exe) is a suffix at the end of a file name that indicates the file's format or type. The operating system uses this information to determine which program should be used to open or handle the file. For example, a .pdf extension tells the computer to use a PDF reader, and a .mp3 extension tells it to use an audio player. The other options are incorrect: file creation time is metadata, not the extension; the extension doesn't indicate where a program is saved; and it doesn't control which file name is displayed.

Answer:

C. What type of program to open
