The correct answer is:
d. F13
Explanation:
1. Function keys on a computer keyboard are typically labeled as F1, F2, F3, and so on up to F12. These keys usually have specific functions assigned to them depending on the software or operating system being used.
2. In this case, F13 is not a standard function key found on most computer keyboards. The usual range for function keys is from F1 to F12.
3. Keys such as Fl, F2, and F9 are common function keys that serve various purposes like opening help menus, saving files, refreshing a page, etc.
4. Therefore, since F13 is not a standard function key on a computer keyboard, it is the correct answer to the question as it does not belong to the usual set of function keys.
