Answer - C - The extension of the file that stores information including messages and calendars from Microsoft Outlook is .pst.

Key Takeaway: Personal Storage Table, or .pst, is a file used to store local copies of messages, calendar events, and other items within Microsoft software, such as Microsoft Exchange Client, Windows Messaging, and Microsoft Outlook. It has a 2GB file size limit. When approaching the 2GB limit, if Office SP-1 is not installed, Outlook becomes extremely unstable, to the point of not being able to click on any message or folder.
