Which key do you press to check spelling? A. F3 B. F5 C. F7 D. F9

The correct answer is C. F7.

F7 is the key that is used to check spelling in most word processing programs. When you press F7, the program will highlight any words that it finds that are not in its dictionary. You can then choose to accept the suggested spelling, change the word, or add the word to the dictionary.

F3 is used to open a search window in most programs. F5 is used to refresh a web page or document. F9 is used to update a document in most word processing programs.

I hope this helps!
