Which key is not an appropriate key to enter the BIOS Setup?

• A. F5
• B. F2
• C. Delete
• D. Esc

Answer: (A)

Entering BIOS Setup happens at startup, and the firmware expects a specific key to trigger it. Delete and F2 are among the most universally supported keys for accessing Setup, and Esc is used on some systems to bring up a boot menu that can lead you to Setup. F5, on the other hand, isn’t a standard key for entering BIOS Setup; in many contexts it’s used for other functions like refreshing or page navigation, so it won’t reliably open the BIOS. That’s why F5 isn’t appropriate for entering BIOS Setup. If you’re unsure, look for the prompt on the POST screen or check the motherboard/system manual for the exact key.
