Answer: Option A. File
Explanation:
A File tab is a section on the Office ribbon of any Microsoft Office products that contains and gives you access to perform file functions such as New, Open, Save, Save as, Print, Share, Export, and Close on a document.
The number and function of the buttons in the file tab varies slightly depending on the application.
