Correct Answer:
A. F5, F6, F7
F5, F6, F7 are examples of function keys. Function keys (F1 through F12) are dedicated keys on a keyboard that perform specific tasks depending on the active program or operating system context.
- Ctrl+Alt+Del is a key combination used for system-level commands, such as opening Task Manager, not a single function key.
- Shift+F10 is also a key combination, often used to open the context menu (similar to a right-click).
- Tab+1 is not a standard or recognized function key or key combination.
