Why each option

Many laptops include a dedicated physical toggle switch for the wireless adapter, allowing users to disable Wi-Fi and Bluetooth without accessing BIOS or software settings.

AExternal display

External displays are connected via ports like HDMI or DisplayPort and have no physical laptop-side on/off switch.

BWebcam

Webcams are controlled through software or OS-level settings, not a dedicated physical switch on the laptop chassis.

COverclocking

Overclocking is a CPU/memory performance setting managed in BIOS or software utilities, not via a physical switch.

DWirelessCorrect

Wireless adapters on laptops commonly have a dedicated hardware switch or button that toggles the radio on or off at the hardware level. This is a standard laptop design feature that predates software-only toggles, allowing users to quickly disable wireless without entering BIOS or the OS. External display, webcam, and overclocking do not have physical switches for this purpose on laptops.
