The best answer seems to be letter A. activate Spelling and Grammar check.
Explanation:
When using the software Microsoft Word, pressing the F7 function key will open a "window" to the right of the document you are writing/editing. The window automatically searches the document for spelling and grammar mistakes. It shows the user the number of mistakes found for each category. You can also have the document checked for more than one language at the same time. When you click on the number of mistakes, you are shown where the mistake is. The function does not automatically correct it, but it provides you with options instead.
